I hope Amorim don't continue giving excuses next season because we are assuming that Ten Hag messed up with the United team before Amorim took over and now that Amorim has been given the opportunity of signing new players to boost his squad he should do and excellent job and get the team working again. Last season is over and no one is judging him by the performance of the team again but he has to task himself and the new player to do well and work to ensure they get back to top4 that should be his major targets next season.
Definitely I don't think anyone can really judge Amorim performance based on last season. It can be argued that the team has being messed up by Ten Hag and he only had the January transfer to fix things up, which I don't think it's okay for him to fix the team.
This season he really does not have any excuse not to improve on last season, because he would have had a total of 3 transfer markets, that's if he survive till January, which I would really want them to give him the chance to prove himself till the end of the season. I believe he will do better than last season, so let's wait for the season to start.
