Talking about teams that are underperforming, Manchester United is a good example of team facing such instability this season with hope of total restoration. There inconsistency this season made some fans lost there faith on the team.
Manchester United struggled with form and consistency at the beginning of the season but now I think they have stepped up a little with hope to dominate by next season
To dominate the next session, MU should think about improving the squad from today. I don't see any significant change after Amorim took over the squad, so this situation, MU should buy another player in order to realize that. MU has a significant problem with pressure. They are used to winning and have won many trophy tournaments in the past. The fans expect a lot of that to always happen session by session, which I think is very hard to realize if The squad and coach don't have chemistry for each other like Alex Ferguson era. Now, what MU should do is how to face it all with full consciousness because when they have too much and have a lot of expectations, they will not realize it in the near future.
Amorim has not been in this team for long, it is indeed disappointing when he can not quickly fix the team, but on the other hand, it seems unfair to immediately label something bad to this coach without giving more time. He came with a very messy team condition, he had to put the puzzle together one by one. In my opinion, giving him a chance for next season can be done, with the note that if he is still unable to bring changes to this team, then the management must make a decision by considering the evaluation of each match of course. But whether the management will give that chance or not to Amorim, we'll just have to see next season.
