I don’t know why people are still doubting Amorim to do something better, after we all have seen indications that he is ready to put all his effort into changing their narrative this season. Although everyone has their reason to say what they wish, I still have hope in him, and I believe he will be able to do something better, because he is much better in terms of improving the team compared to Erik ten Hag.
Amorim's reputation will change if he succeeds in turning the current team he has into something extraordinary. We know how poorly United performed last season; even a slight improvement will be very noticeable. They have some new players, and we will see their performance for this season. Hopefully, the results that Amorim will show are something positive. If not, his career with United might come to an end.
Amorim has handled Man United in several matches last season but there were not many changes to Manchester United's performance so it is natural that many doubt Amorim especially to oversee next season there are not many changes in the Manchester United squad so it is likely that their performance will also be the same, there is no significant difference compared to last season.
