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.
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.
