It is difficult to predict who will be able to win the Europa League and we can even see in the last few seasons there have always been surprises that have occurred so for this season too, Manchester United does have good strength after firing Ten Hag but we also should not overdo it because their new coach Amorim still needs time to adapt to be able to build the Manchester United team.
And for the defeat that Manchester United just experienced against Arsenal I think it is a natural thing because Arsenal does have much stronger strength than Manchester United.
I agree with you that we should not overestimate a team that has a new coach, because this is also just the beginning and I personally will not be quick to conclude something on the performance of a new coach. In addition, the European League often shows surprises which we can see almost every season, especially who the team becomes the champion. For example, last season, how many people really favored Liverpool and Leverkusen to become champions, but at the end of the season, Atalanta managed to become champions, which in fact at the beginning was not more favored than the 2 teams I mentioned.
