It is important for Manchester United to get their game in order before thinking about achieving higher goals, because they still look very weak against strong opponents. As for Amorim's work, it seems to me that he pays more attention to working within the team with the players, as an example, the absence of Rashford, which indicates that there is no order within the team, maybe he is trying to work with the players, because I do not see any changes on the field at Manchester United.
In the Europa League, Manchester United's performance has indeed improved slightly compared to their performance in the Premier League so that many people doubt Manchester United's performance to compete for the title because there are still many weaknesses that Amorim has not been able to overcome. He is strict with the players and even previously Garnaco and Rashford were rested because they did not show a good attitude when working with their teammates, although in the end Garnaco was played again. But especially for Rashford, he has a much bigger problem and rumors are that Manchester United are ready to let him go if an offer comes in.
