Man United chances are very small compared to other favorite teams, their performance is not yet completely stable, making them not really considered in this competition. Yes, maybe they can make it to the quarter-finals or even the semi-finals, but that would be their best achievement in this competition as they are still behind other teams. In fact, Man United has complete players, but due to the management of the squad not being up to standard, it is difficult for their performance to improve.
If we judge from Manchester United's performance in the current domestic league, it is natural for many people to doubt the team going far in the Europa League this time, but I personally still have no doubts about their efforts to be in the next rounds in the Europa League competition this season because here the opponents are slightly different from those in the domestic league. So I still believe in Manchester United's current abilities even though in the domestic league their performance is still far from satisfactory.
Mentality might be a factor that will help, that is if their mentality is very good. But looking at their performance this season or previous seasons, I can conclude that they are not a club with a mentality. They are different from the Manchester United we used to know, in the past they were a club with a very good mentality, they once made a miracle in the Champions League final against Bayern Munich where they were able to turn things around in a short time. But then again that was then and now they are not the Manchester United I used to know.
