Manchester United has a bigger problem than just a few players, or even just manager, they have a management problem that is taking them longer to fix which is going to be very hard. I understand that if they change their manager then they could be a little better, but even if you get Pep Guardiola here, doesn't mean that they are going to win the league, or if you gave the entire city squad here and trade all united there, still they are not going to be the winners suddenly with the same manager and management.
This is why they will need many years, but eventually they will fix the squad, change the manager and have better management, only then they will do fine. Until then, they are going to just try to keep gradually and slowly become better.
It is true that Manchester United is currently in a very disadvantageous situation because I think they are even worse than the previous season. I don't know whether this will happen to Ten Hag or not for his fate, because as far as I know Manchester United did give Ten Hag the opportunity to prove himself but if Manchester United continues like this maybe his career at Manchester United could end.
You are right, maybe by changing the manager they could be a little better, but for now I think it's too late maybe Ten Hag himself has to be able to prove it even though it takes a long time.
So I think Ten Hag has to be able to prove that he is able to bring Manchester United to be better than the previous season and in the current situation, because Manchester United's current ranking is very disadvantageous.
Manchester United has given lot of financial support to Ten Hag to be able to improve and increase the team performance this season, even Manchester United still maintains it even though some time ago many people expected Ten Hag to be fired and replaced with better coach.
Now everything has gone according to what Ten Hag did, many major changes in the line-up and in fact for the beginning of this season what Ten Hag did has not really been seen, but this is still early and there is long time ahead to finish the season with all the changes that have been made.
If the results are possibly much worse then there is clearly chance for Ten Hag to be fired as coach next season, we just see how things develop, I hope Manchester United is not much worse than last season.
On the other hand they are also in the Europa League competition and with conditions like this I am not sure Manchester United can compete well there if they do not start to improve and restore their performance.
