If you see it that way I wonder what the Chelsea fans would be thinking at the moment if they are seen as the team that is being favored more than the others, it is either they shout out loud that Arsenal are the most favored in all competitions than other clubs. Well is even hard for Chelsea because they see any club they face as a difficult side to beat, imagine how they struggled to play till the whole of 90'mins and extra time too, it doesn't show any sign of them being the World Club champions, that title fell on the wrong hand, PSG would have won it. The FA Cup and the other are as important too because is better to hold on to something this season than end the campaign with nothing but for Arsenal they need to win the EPL title without any questions because they have fought really hard for it, they deserve it.
Any team that deserves to win a trophy must be prepared to face whatever opponents given to them after the draws. Chelsea fixture is not a difficult one, neither it is an easy one. If Chelsea deserves to win the FA Cup, Port Vale wont stop them. After the draw, Arsenal fixtures is more of an easy one compared to the rest. But, like i said earlier, a team like Southampton might become very hard to defeat. Mansfield and Wrexham opened my eyes to see how lower division teams, becomes a threat in European competitions.
I like what you said and having Chelsea in this conversation makes me wonder why they brag about being the Club World Cup winners? The energy I expect from them is not there to balance the title and the club that was given to Chelsea could be worse than their previous opponent, with Port Vale getting ready for the Blues I just have to be honest, I want Chelsea to be eliminated so that the complains would reduce a little and they'll channel their frustration on Manchester United for topping them on the EPL table.
For me no team is easy especially if the bigger side are the threat of the smaller side progressing to the next round. Arsenal have been the favorite and is a problem not to their opponent Southampton but to their fellow EPL teams that are still active. Should anything happen that they miss out on this opportunity I think it will annoy Arteta and equally the players because their target is to win all 4 titles this season without missing any.
