For now, Man United still has a chance to break into the top four of the standings, because they are only 6 points behind Chelsea, but on the condition that they must rise and perform consistently in the future and hope that one of the top four teams stumbles. Regarding Ten Hag, his words cannot be fully trusted, he is very good at spreading sweet promises to fans after the match is over. Regarding player injuries, Ten Hag should be able to experiment to reduce the burden on players in the main squad, in order to minimize injuries.
After losing badly to Tottenham, it is certainly difficult to rise and get full points at Porto home. If The Red Devils manage to bring home 3 points from the Europa League, that's right, their next match against Aston Villa in the Premier League is very troublesome. Moreover, considering the strength of Unai Emery squad which managed to beat Bayern Munchen in the Champions League, it seems that Ten Hag will have big problems in the two matches. In short, it seems that only luck can save Ten Hag position at Old Trafford.
For now the last thing Manchester United should be thinking is finishing in the top 4, they have a bigger problem than finishing in the top 4. The team performance is 100% poor and they are not sure of even advancing to the next stage of the Europa league, with how annoying they play even the fans are just hoping for something new to happen not winning a trophy but let the madness in the house be cured because you can't compare Chelsea and Manchester United not with position or with points on the table.
The Blues issue is like a disease, when it comes it will have to make them lose points like they're just being transferred to the EPL, after sometime they'll regroup and start performing well again but for now Manchester United can't over take Chelsea before the end of the season, highest both teams will not see the top 4.
You talk about ETH, he hasn't been a coach to the UTD team but a man who cares less about his household, ETH is not ready to set the house in order but he plans on giving the fans what they want to hear when talking to the press, his words are very strong but it works against the club. He doesn't care who is injured or not, all he has in mind is let them go and disappoint themselves, he has no feedings for the club anymore.
Aston Villa is no longer the team Manchester United can go all out and get an easy win with much goals. The Villains went out to secure a 1nil win against Bayern Munich who have been banging goals winning games without minding their next opponent, if it was Man UTD they won't have won Bayern and this is what's going to happen when the Red Devils visit the Villa Park, it would be Aston Villa making sure they beat Manchester United to secure another win because the spirit of Aston is very high after winning Bayern Munich so UTD can only beg for a draw not a win.
