The team is not yet complete and there are still some shortcomings, which Amrim himself probably knows. But we have to accept that it is not realistic to solve all the problems at once. They have lost two matches of the season and this reflects their shortcomings. They are looking for a goalkeeper, which I think is definitely a necessary step. They also need to think about some other positions which will take time. They have had some problems with scoring goals. Now let's see how Amrim deals with this. But I think they played relatively well against Arsenal. They should have won the last match.
With situation of the club, lack of competitiveness, it's really hard for them to convince star players to join them. They are facing with similar problems like Chelsea, Manchester City and PSG years ago when they suddenly got rich and had abundant money as well as budget for player transfers but they had to choose tier-2 star players. Manchester United must improve their performances, ranks and be eligible for Champions League next season in order to be attractive with Tier-1 star players.
After Manchester United spent a lot of money in the transfer window this season and they still failed to compete then I believe the manager is the main problem we don't talk about his ability, it's just that sometimes a coach is not suitable for all clubs. I'm sure Amorim doesn't have much time to fix this situation and yeah at least until mid season his fate will be determined. Manchester United have dropped 5 points in their last 2 games and we still have to wait for the next 3 games to say something.
Manchester United spent a lot of money but they failed to find good head coaches and players who can work together and make up a strong squad for their club. They also did not have good strategy in club development and sometimes they lost faith in good head coach like Jose Mourinho while trusted wrongly a star player like Paul Pogba who has never satisfied their club expectation and trust on him.
This way, they have failed in many years since Alex Ferguson's retirement but they have changed to maintain trust on Ten Hag - who finally failed to do his management job well for the club, and in the last season till now Ruben Amorim. This season has gone only two matches in Premier League, results are disappointed but I think they must give Ruben Amorim more time and chances. If they sack him in coming weeks, they will step in similar strategic mistakes like many recent years.
