But that is natural because it is not easy to lift the performance of a team from the bottom instantly, it will definitely take a process. However, I also agree that some Manchester United players are not at their best level, there are players who have not been able to show their best game and some are slowly showing better. This is a challenge for Amorim to solve the problem.
Aside that, people are quick to forget that it's not easy to take up a team mid season and introduce an entirely new tactical system different from what they're used to. There's no preseason and time to blend the players. Amorim is doing is best and I think he'll keep testing his players in the rest of the EPL matches while his main focus will be on the europa league because that's their only shot at champions league football. About underperforming players, I believe he's assessing the team and taking notes. At the end of the season, players that do not fit into his style will be released to make room for new ones.
There are so many things that need to be overhauled by Amorim, since the Manchester United team changed coaches I think the problem is with the players not the coach, the Manchester United players seem to have no strong motivation to win the match and the current players do not have strong chemistry with each other so the performance is very chaotic.
I think Manchester United management should follow what Chelsea did, overhaul all the existing players and start a new process, because so far Manchester United management has spent a lot of money to bring in several new players but they have not gotten any results.
