Overall, the play directed by Manchester United's players has improved, although there are some weaknesses that still need to be addressed.
Defense remains a problem, and Amorim still needs a lot of work.
Some attacking patterns also need to be evaluated, as several scoring opportunities were missed and there are still some issues with finishing.
If Amorim can evaluate the positions he considers weak, then I'm sure Manchester United will be even better next season, as we can now see their much more competent play.
I agree with you, Manchester United's performance has improved from the friendly games we've seen so far. Of course, there are some issues at the club that the manager must address before the season starts in a few weeks, otherwise, they will continue to struggle in the Premier League. Manchester United continues to have a poor defensive, conceding unnecessary goals in games where they should be keeping a clean sheet, like yesterday match against Everton, where some mistakes were made by the goalkeeper.
Furthermore, Amorim is not putting some of his players in positions where they are most comfortable. I do not expect Amad and Mbuemo to start a match at the same time, instead I expect Amad and Mbuemo to compete for the position so that we can see goals and the best from both players. I don't expect to see this type of formation in the Premier League games, he must use their defense to prevent them from conceding goals. They cannot win a single match without a penalty.
