Amorim might not be getting good results from EPL matches but he is doing pretty good in Europa, because United can defeat most clubs in Europa if they are determined to do so. Amorim should be scouting around looking for players that will be able to give him what he wants with his game strategy. I just hope that United can go far in Europa so that Amorim can use it to encourage himself.
In addition to the things and hopes you said, I also hope Amorim will make some other good strategies by targeting some new players in the January transfer market because if they only have the players like now, I doubt Manchester United can improve their position in the Premier League standings even though they might be quite good when competing in the Europa League this season. Because in yesterday's match Manchester United lost to a team that is ranked quite close to the relegation zone so Amorim still has to make more maximum improvements for Manchester United so they can go further in the Europa League this season.
The squad Amorim wants is not at Manchester United at the moment. That's why Amorim's adaptation process is taking longer, but it's not his fault because Amorim didn't bring these players to the team. The important thing is whether Amorim has learned from the games. The sooner he realizes that these players are not good, the better for Amorim. Otherwise he would have to face the same fate as his predecessors. There are successful teams in the Europa League. This season Athletic Bilbao and Lazio are both doing well in their league and in the Europa League. Manchester United, who still have serious problems with the squad, the structure of the game and the players, will find it very difficult to progress in the Europa League.
