Manchester United still have to make a more accurate improvement in themselves in this season and if Manchester United is able to make a more attractive surprise in the European League this season, I will also not be surprised by that. Because it is true that as you say that in the European League it is always quite difficult to make predictions from the beginning because of the changes can still occur through every surprise in a team that is not favored so far. Lazio is already quite great in the European League this season, but teams like Lyon, Galatasaray and Tottenham Hotspur must also be watched out by Lazio.
In the Europa League Manchester United has improved slightly after Amorim became their coach but there are still many changes that need to be made because so far Manchester United's performance has not been stable. Amorim's motivation may be very high in the Europa League because in almost all competitions they have lost the opportunity to achieve a trophy so that only the Europa League is the only hope they can realize when they are able to play much better in the future.
Another challenge is only in this competition the opportunity for Manchester United to qualify for the Champions League by winning the Europa League and will give them one ticket to qualify for the Champions League. The tight competition in the Premier League makes it difficult for them to break into the top four, making it difficult for them to catch up with the points collected by several teams in the top five.
