So you mean Manchester United is a team that must be considered to win the Europa League title?
Now Manchester United is in the quarter-finals and they are undefeated but I don't think Manchester United will be overly favored because their overall performance is not that strong and also consistent so Manchester United is still the same as other teams in terms of percentage and overall also some teams have the same strength so they have the same chance to win the Europa League title this season.
Manchester United's performance in the Europa League is indeed worthy of being considered as one of the candidates who are quite favored. If you have ever watched Sevilla when they came out as champions in the Europa League but their performance in La Liga was also quite bad. It is natural when many people consider Manchester United as a candidate for champion because they are still quite consistent in the Europa League even though in the English league itself they play quite badly.
Overall Manchester United has the opportunity to come out as champions but they must show consistency until they reach the final and their ability in the Europa League is the best so far because they are undefeated.
