Amorim's team still needs some more powerful players to be able to support the team's performance for a better direction, because Amorim does not have to be fully blamed in this matter because when Amorim was designated as Manchester United coach, the team was also not in good condition. So it is very feasible for Amorim to be given even more time in order to prove that he has a good ability to train this team.
more precisely, it is indeed giving time for Amorim before we judge his performance because so far Amorim has only continued what Ten Hag has built and it cannot be denied that Amorim came when the Manchester United team was quite down.
This season in the Premier League there is no possibility for Manchester United because they are too far behind and now Manchester United has shifted its focus to the Europa League competition because that is the only possibility they might achieve.
And regarding Amorim's performance, I am quite sure that if he is given a lot of time to process and is supported by Manchester United management to build this team, it is very likely that Amorim can make it better.
While it is true that Amorim took over a terrible team, and didn't made any decent moves during winter break neither, just sent some away but usually nothing big happened during this period. It means we are not seeing if United could be any good, it is going to be a tough deal without a doubt and we can't really consider Amorim any good neither.
Sure, he couldn't make any moves so judging him at this moment would be unfair, but there were absolutely zero improvements under him, there could even be an argument made that he played them worse than ETH, so how could we just say he is decent? Next season, after a summer of moves, if he still looks like this, he won't see the end of the league, he will be surely fired for sure.
