UEFA Champions League 2023/24 Season

[Google+]

I know Arsenal are favorites against Porto, but are you sure Porto doesn't want to win the match and qualify for the round of 16. Porto have so far proven themselves to be one of the contestants in the Champions League, having only suffered 2 defeats in the group stages. They have a good mentality to compete against Arsenal and Porto should not be underestimated in terms of their chances.

Porto's chances are certainly not as good as Arsenal's in the Champions League, but Porto is a team that has productive attackers. Porto scored 15 goals in 6 group stage matches, which is almost the same number of goals scored by Arsenal in the group stage. I can't necessarily underestimate Porto, especially at home, so I hope the first leg will be an interesting match.

Porto has a good reputation in the Champions League, Arsenal must not underestimate this match if they have the ambition to reach the quarter finals. In terms of squad depth, Arsenal really deserves to be at the top and they are in stable performance at the moment. Porto is lucky because they act as hosts, but their chances of beating Arsenal are very low, betting on Arsenal winning will be safer. I think Arteta will not waste this good opportunity, they have good capital after beating Burnley in the Premier League.

This season Arsenal appear more aggressive than last season, the depth of Arteta squad increases their bargaining value in every competition including the Champions League. The consistency shown by Arsenal in the last few matches shows that their chances of winning over Porto are quite big. On the other hand, it is possible that this match will end in a draw, or Arsenal could also experience defeat even though many people favorite them.

For me, I feel like Inter has been doing amazing recently and I think they could beat ATM as well. I know that this isn't some new information and everyone thinks so, but we have seen upsets in UCL just recently. Like how Bayern ended up losing to Lazio.

I concur with your point, having a single loss in 24 round of a game in a season is a green flag for them to remove Atletico Madrid from this knockout face, not only that, the last match the had was in favour of Inter and that was when they were even struggling in the top 4 in Seria A but as it is right now, they don't look like a team that is struggling because they are now sitting at the top of the tree looking like elephant that can smash any animal that comes under their toes.

I do not think that the gap is that big ,and yet Bayern still lost, so if Bayern is much better than Lazio compared to how much better Inter is than Athletico Madrid, then it is decent to say that another upset is possible. But, even with that in mind I still think that Inter will win this one, it is not going to be all that possible. The best thing to do at this moment would be something that could benefit everyone, that should be what we could possibly bet on.

Beyerm deserve to win that game but they weren't quick as Lazio did. Having a goal sometime in a match is a very good advantage, score a goal and then make your midfielders communicate perfectly with Defense and forward, you will win that without struggling because your opponent don't get the chance to convert their ball to chance, that was what favour Lazio. As we are thinking that a single goal is little, let's see if they don't concede another goal in the second leg because the come back might not even happen.

Porto's performance in the Champions League group stage was good. The team was a relatively weak group. Shakter and Antwerp were in the group. So it was quite easy for Porto to qualify for the knockout rounds. However, they will face the mighty Arsenal in the knockout round. And Arsenal are in great form right now. Arsenal players are now very confident after the win against Liverpool a few days ago. It is difficult for any big team to beat Arsenal now. My guess is that Arsenal will win against Porto by at least 2 goals. However, if Porto plays a defensive strategy, it will be difficult for Arsenal to score.

They are a subscription club in the Champions League but indeed if you look at the naked eye with the composition of the actual players it is quite difficult for Porto to stand further in this case especially with Arsenal's condition in domestic competitions which are still quite good.
Indeed, the match for the first leg in the Champions League round of 16 can actually be a good thing because Porto play home but Arsenal are also currently in a positive trend and their goal productivity is still very good now.

This could be a stumbling block for Porto and I personally for now am still quite confident in what Arsenal will do in this match because they can definitely overcome the resistance that Porto is doing because after all it is difficult for Porto to force a victory even though the match for the first Leg this time is played at the Do Dragão Stadium which incidentally is home to Porto.

But Arsenal's opponents will be very difficult. Arsenal's current game is good again and very consistent in winning with the score has been the last opponent of Burnley and West Ham despite playing away to his cage Westham and Burnley were able to win with a landslide score of 5-0 and 6-0. while FC Porto in the Champion League is a weak team opponent only Barcelona is strong and even then when meeting with Barcelona 2 home matches and both parties ended in defeat.

The victory of Lazio was not because of the luck or anything like that because I think it was all because of the weak performance in Bayern Munich. Even if we consider Lazio at their~ best form we couldn't imagine seeing Lazio winning this match beat Bayern Munich easily like that.
Bayern Munich hired Tuchel to win the Champions League against much stronger teams and that's funny to see them losing against Lazio.

Lazio managed to beat Bayern munich because they were able to take advantage of Bayern munich instability after losing to Leverkusen. Yes, even though it is very unlikely to be affected, what we saw was Bayern munich performance in that match which really looked quite bad. I think Lazio has a good chance, but even so, Bayern munich are very strong when playing at home, so the second leg is still quite difficult to predict the final result. Bayern started to lose their toughness even though in the group phase they appeared quite impressive by being unbeaten.

Well, many are speculating that Bayern munich will be a candidate to win this season, but if Lazio manages to beat Bayern munich in the second leg, of course those who think Bayern munich are very strong will find their hopes dashed very quickly. Apart from that, Tuchel is starting to get stressed at the moment because if he fails to get Bayern munich to win the second leg, he could be fired.

But, even with that in mind I still think that Inter will win this one, it is not going to be all that possible. The best thing to do at this moment would be something that could benefit everyone, that should be what we could possibly bet on.

Yes, it looks like the Serie A teams at this moment have a good chance of winning because, even though Atletico still looks fine, but in reality Atletico does not have a completely stable performance. Therefore, because Inter's trend is still very good until now then yes, I think it is appropriate for Inter to be favorites, especially in the first leg because Inter will play at home. So yes, with these factors, maybe I won't miss this good opportunity to choose Inter to win the bet. Because yes, I gain confidence after considering that Inter has a trend that is still good and stable until now, and of course that is a good foundation for Inter to be able to beat Atletico in the middle of the week.

With the performance that Inter have now there is actually a pretty good chance they can get a win in this match but of course they must realize that this is Atlerico and of course we must be aware that there is already some information that has been collected respectively to get the best scheme in this match.
Atletico are currently in trouble because indeed their internals still cannot be fixed properly by Simeone but their experience of meeting Serie A clubs in previous titles that have happened can be a good thing for especially we know that Morata is now in Atletico's uniform so surely more or less he must know what he has to do in order to make Inter falter and in order to make Atletico get a victory in the first leg this time.

[bbigtart]

Inter is the favorite because they're really good lately with 5 consecutive wins (all competitions) and they play at home in this 1st leg. For the 2nd leg, Atletico definitely will be the favorite.
Because of that, Inter must win with at least 2 goals difference to make it easier for them in the 2nd leg later.

Some people said Atletico might not in a good performance right now, after failed to score in their last 2 games.
But Simeone famous as the master of defensive style and counter attack - so a draw is still possible.

The Inter vs Atletico match will certainly be hot and indeed Inter are the favorites to win this match, but we also shouldn't underestimate Atletico because this match can be said to be a tactical duel between the two coaches, a physical duel and a pressing duel will occur in this match.

Atletico is different from previous years, they tend to attack rather than defend, while Inter are getting better at defending and quicker at counter-attacking. This can happen to us in our respective leagues, Inter is heading towards the championship ladder, Atletico is trying to stay in the Champions League zone for next season. My prediction is that Inter Milan will win this match with a score of 2-0.

This match ultimatly not easy for Arsenal, but Arsenal have great chance to won. They a favorite team at this match rather than Porto, of course even Arsenal not guaranteed to win in an away game. Porto will bet their fate against one of the favorite teams this season, but I think Arsenal is not completely reliable even though the team's performance is very good. Maybe it's not an interesting match to look forward to, Napoli vs Barcelona is certainly more interesting in my opinion.

Bayern Munich hired Tuchel to win the Champions League against much stronger teams and that's funny to see them losing against Lazio.

In principle, winning and losing is a normal thing even for strong teams. there are various causes and they can be very diverse, or one mistake can have fatal consequences for the team as a whole. Talking about Lazio's match against Bayern Munich, if one of Bayern's defenders doesn't make a mistake. So, Lazio will not benefit from being awarded a foul at the penalty spot. Statistically, Bayern Munich controlled the game. Instead, Bayern created 17 total shots. Unfortunately, not a single shot was on target and only had 1 big chance. In general, Bayern Munich's performance is not what it should be. even though Musiala, Muller, Sane actually played the game quite well. but unfortunately, Kane was unable to perform well at Lazio headquarters. In the end, Bayern lost in the first leg.

We agree, if the club's target is to choose Tuchel to handle Bayern Munich to achieve the Champions League trophy. but unfortunately, the journey did not meet expectations. Unfortunately, in an important match, several players who Thucel usually relies on were injured. however, the home team's performance was not that good. But, this is football. In fact, Bayern lost at home to Lazio. well, in the second leg later. there was no choice but to overthrow Lazio with a fairly crushing goal margin..Before the second leg match is held, Thucel must prepare his team to perform better and fix the weaknesses of his team.

This match ultimatly not easy for Arsenal, but Arsenal have great chance to won. They a favorite team at this match rather than Porto, of course even Arsenal not guaranteed to win in an away game. Porto will bet their fate against one of the favorite teams this season, but I think Arsenal is not completely reliable even though the team's performance is very good. Maybe it's not an interesting match to look forward to, Napoli vs Barcelona is certainly more interesting in my opinion.

No match is easy in the Champions League knockout stage, but with the form Arsenal is on, I cannot doubt their winning in this match. I am very confident and certain Arsenal will win FC Porto and they will be among the Champions League title favorites if they do well in this stage.

If we flash back to the h2h between Arsenal and Porto, you will see that the last five match result was equal as both team won two and they drew one; therefore, both of them have the chance to advance to the next level, but Arsenal is on fire and can win the match and finish the stage in the first match.

Arsenal lately has upgraded in terms of form and performance, I agree with you to some point that Arsenal will win, but this game still looks like a 50/50 game to me, and besides FC Porto is not a Champions League baby team to just win so easily. The got experience too like Arsenal and this phase of the Champions League competition has entered its crucial stage and no team wound find it easy to win any game going forward. I find it difficult to choose a favorite team to win in this match.

But Arsenal's opponents will be very difficult. Arsenal's current game is good again and very consistent in winning with the score has been the last opponent of Burnley and West Ham despite playing away to his cage Westham and Burnley were able to win with a landslide score of 5-0 and 6-0. while FC Porto in the Champion League is a weak team opponent only Barcelona is strong and even then when meeting with Barcelona 2 home matches and both parties ended in defeat.

Arsenal is in a very good form currently so their opponent wouldn't really be much of a problem to them they may be able to get ahead in that game judging by their most recent performance as they have been winning a few games and has also performed so well in these games they have been winning so far and I think it's a boost to their confidence.

Since it's looking like they don't have a very good chance in their premier league games, they may try to see what they can do in the champions league where it looks like they have got better chance as it's looking like all the teams in the champions league has got equal chances since they are all still at the round of sixteen, beyond this stage we can tell teams with better potential in the champions league than others who may have managed to get pass the round of sixteen too.

That wont be any stress to Inter. Obviously they would win if they play very well. Still, they should be  prepared because Atletico will not make it easy for them to get away with the points. Atletico on the other side is also getting prepared. The UCL has not been easy since it has been difficult for bigger teams to succeed.

You are right this will be an easy win for Inter Milan. They have managed to lock in the title after Juventus were held to a draw by Verona last night. The draw made the difference 9 points but if Inter are able to win the match against Lecce then it will be 12 points and I think Juventus have lost their motivation to chase the title. So Inter Milan can play without pressure in that match and by looking at the performance of both teams in the last few matches, I bet on Inter Milan winning.

It's a big advantage for Inter Milan, who don't have fierce competitors in Serie A, so they can fully focus on the UCL.
With the quality and consistency that Inter Milan currently has, they are really worth considering, apart from the results in the group phase which were a little disappointing, we can see that Inter Milan's performance is increasing and this is clearly visible in the domestic league matches they play. and that will have quite an impact on the matches they will play in the Champions League too.

this is what we want and the supporters want perfect results from Inter Milan and previously I said here that when Juventus started to improve their performance to get closer to the points that Inter had, I said that Inzaghi had to immediately set a strategy to be able to get comfort in the UCL by providing a point difference. which is quite a lot for Juventus and after that Inter Milan can focus more on competing in the UCL like last season they were able to reach the final round because they didn't have any pressure.
This kind of comfort is what allows a team to prioritize UCL matches but still be able to win the title in the domestic league because the large difference in points from the teams below means that Inter will not have too much difficulty continuing to maintain their position and the main players will be prioritized in this UCL.

but even though Inter has this advantage, the competition in the UCL will not be this easy even though there is no pressure whatsoever, but you have to be careful when playing against Atletico Madrid, who are currently in good condition, although not as good as Inter Milan, but Inzaghi has to look at the defense. Atletico Madrid is famous for its very strong defense.
So Inter Milan's current mission is just to try to beat Atletico Madrid by maintaining the aggregate score.

Arsenal is in a very good form currently so their opponent wouldn't really be much of a problem to them they may be able to get ahead in that game judging by their most recent performance as they have been winning a few games and has also performed so well in these games they have been winning so far and I think it's a boost to their confidence.

It is true that Arsenal is indeed in the best performance in the Premier League won in the last 5 matches but this time the opponent is FC Porto a team that has a good record when playing at home, it's clear this isn't easy for Arsenal and I'm not sure Arsenal can win, it's possible this match will end in a draw. Arsenal can only take the opportunity when playing in the second leg therefore in the first leg Arsenal must try not to lose. I predict there will be more than 2 goals in this match because FC Porto always plays aggressively.

My prediction is that Inter Milan will win this match with a score of 2-0.

Of course, the match between Inter and Atletico Madrid will be tight and very interesting. It cannot be denied that this will not be an easy challenge for the two of them once they enter the round of 16. However, in the first leg which will be held at Inter, Inter should win by optimizing this home play. The chances are bigger, especially now, Inter's game is getting better and they are very strong in various lines. So, they can at least beat this team from La Liga quite well.

But on the other hand, Inter also cannot underestimate their opponents. because after all, Atletico Madrid is not a small team. Moreover, they seem to have very big motivation in this match, at least they won against Real Madrid, so they have pretty good confidence when they face Inter later.

In my opinion, Inter will win, but Atletico Madrid will also score. 2 -1 maybe, will it happen?

It looks like Porto will indeed have difficulty facing Arsenal in the last 16 first leg. Because Porto currently appears to be experiencing a decline in performance in the Portuguese league, or it could be said that their consistency is decreasing. Meanwhile, Arsenal has actually had very significant improvements recently. And Arteta seems to have found a strategy that can make Arsenal have high productivity in scoring goals while keeping the defense solid. All of this was proven in the Arsenal vs West Ham and Burnley matches where Arsenal scored many goals without conceding a single goal. Even Arsenal has also been able to beat Liverpool. And I think there is no doubt that Arsenal is the biggest possibility of qualifying for the next stage. Because I predict Arsenal will win in leg 1 and leg 2.

These two teams are experiencing different performances, Arsenal has been very consistent in the last five matches in the EPL, the consecutive wins achieved by Arsenal are good capital in continuing the UCL. Meanwhile, Porto is inconsistent in maintaining its performance, in the last five matches they were only able to achieve three wins, one draw and one defeat. Arteta is very enthusiastic about this game, he will direct his players to play like when they beat Liverpool. Arsenal's goal productivity is a threat to Porto, even though Arsenal's status is the visiting team in this game, they will be able to control the match with the good capital they have in the last five matches.

Mentally and in experience, I tend to see Porto as the favorite in this match, but Arsenal also cannot be underestimated because every season they make many changes. Porto has experienced a decline in performance in the league, but it will be quite different when playing in the Champions League and I don't think Arsenal will win easily because Porto is a team that can always give surprises in the Champions League. Arteta needs to provide high motivation to his players because not winning enough big matches and not conceding in the local league can be an advantage in the Champions League.

The first leg will also take place at home to Porto and this will be an advantage for them to have much greater support from the fans. If Arteta is unable to win the match then I think the second leg will be much more difficult even though the match will take place at the Emirates Stadium.

[rendravolt]

Arsenal is in a very good form currently so their opponent wouldn't really be much of a problem to them they may be able to get ahead in that game judging by their most recent performance as they have been winning a few games and has also performed so well in these games they have been winning so far and I think it's a boost to their confidence.

Arsenal can only take the opportunity when playing in the second leg therefore in the first leg Arsenal must try not to lose. I predict there will be more than 2 goals in this match because FC Porto always plays aggressively.

Talking about Porto, they are indeed that strong when they are at home and that is a fact that we know so far. Porto can always win at home and their record so far is only losing 1 and drawing two when playing matches in the domestic league. This is a positive record for Porto and of course they will remain confident even if they face Arsenal in the first leg.

Trying not to lose might be the main solution that Arsenal must put forward and I think they can do it if they only draw. However, if the Gunners lose, it will be quite troublesome in the second leg because Porto will focus on a stronger defense when they are at home to Arsenal, specifically in the second leg. Matches with equal strength like this always provide a lot of goals and it depends on their defense whether it is easy to break down or not and maybe even if it is equally difficult it could be a draw even without a goal.

Arsenal is still consistent in the domestic league and this gives arsenal more confidence to win the game in UCL. it will not have strong opponent as well, arsenal will get multiple advantages in the upcoming game. No doubt that this club can qualify for the next stage easily but the club shall not need to underestimate porta.
It can also give us a surprise too. The gunner shall always be careful with it. Im only thinking that if porto can only playe fully defensive against arsenal. The quality of players were the main factor that pressuring porto to play carefully against arsenal.

Im not saying porto was weak but this is the only possible solution for this problem. The club needs to make sure arsenal will not be able to entering into the penalty box. The mistakes that very often made by clubs in EPL to play openly against arsenal.
Rather than improving, this is exacerbating the situation compared to its previous state. Considering the circumstances, it appears that Arsenal will need to work harder in order to obtain a ticket and advance to the next round.
