I'm afraid getting a ticket to the Europa League next season will be quite difficult for United considering their performance in the Premier League. If Amorim wants to build his own squad, then we will see some players leave United first and some will be brought in. The situation is unlikely to happen in a short time. Amorim will do it gradually and adjust the club's finances. Maybe United will not easily burn their money like they have done in the past.
It will be even more complicated because it is impossible for Manchester United to get players according to Amorim's needs in the near future so this can affect the team's performance in the competition in the League. Even winning the Europa League is still quite difficult for Manchester United because the team's condition is not so consistent and they will get a much tougher challenge when facing much tougher opponents. Amorim's situation in changing the team to be stronger is not easy because they have to sell some of the existing players first and after that buy some of the players needed and the club's finances must also be adjusted first.
So if Amorim has difficulty bringing United to win the Europa League trophy, then everyone must accept that United may not compete in the Europa League or Champions League next season.
Currently, United's position in the Europa League is quite safe, but in the next round who will know the results? The opponent will be stronger, if Amorim does not manage the current team well, then they could be eliminated at any time.
I think Amorim's hope is only to try his best in the Europa League. Nothing else.
If Amorim wants to play in the UCL next season, he must do everything in his power to win the Europa League title, as that is the only way for Manchester United to compete in the Champions League the following season. I'm not sure what the fundamental reason is why Manchester United consistently performs poorly in some games while winning others. I always think about it and am astonished. They won their last Europa League game against Rangers and also won the league alongside Fulham. They clearly demonstrate that they are slowly regaining form. However, the Europa League is not a league tournament. If Manchester United meets a big club now, they will undoubtedly be defeated with how they are playing currently.
Amorim is doing his best, and I'm not sure what will happen to Rashford. I'm not sure if he'll sell him or loan him out to another club, because since Amorim arrived, he hasn't been involved in the substitutions or even in the lineup. The greatest thing he could do is go. Since Barcelona is interested in him, he can probably cut his pay so that they can acquire him because Barcelona does not have a large budget to buy players like Rashford, and the windows will be open this week probably.
