I think there are some structural mistakes in the Manchester United team which the coach of the team has failed to correct so far. First, find out why the team is performing poorly and then work on them. I think Manchester United team management are working on those things.
Manchester United has experienced decline in performance in the last few seasons but when Ten Hag was appointed as the new coach for Manchester United all of us fans hoped that there would be big changes that Ten Hag could bring to Manchester United.
Maybe what you imagine is easy by finding out and fixing it but actually it is not that easy because there are several errors that may not yet be clearly visible and the way to solve them has not been found.
Just look Ten Hag has tried to replace several players with young players but all of this has not provided any significant changes or developments for the Manchester United squad.
Who knows what they will do in the future but Ten Hag and the team management must immediately improve if they want to survive longer for UCL because here there are very strong teams in every league that are difficult for Manchester United.
