The Manchester United team has only been built for a few seasons by Ten Hag and it is very different from Manchester City, I don't think it can be compared and in the future I still believe that if Ten Hag continues to make improvements and cover up the mistakes that have occurred then it is very likely that the Manchester team will United will be perfect again or match Manchester City's level for the title competition.
But, Ten Hag only have a year to build Manchester United, I don't think he can. If Manchester United didn't qualify for Champions League in the next season, I'm 100% believe they will sack Ten Hag ASAP. And then, the problem can't be resolved since the team always change the team for every one or two years.
The best solution is to sign Pep Guardiola or Ancelotti, because if they failed to bring Manchester United glory, the fans will blame the players instead of the managers, so they can survive and build Manchester United for many seasons.
This is ten Haag's last season for Manchester United if he doesn't prove himself well. This manager has been in charge of Manchester United for a long time but he has not been able to show any significant changes for the team so far, yet Manchester United has trusted this manager for one more season. In the next season, if the team cannot be in the position of 1 to 5 under this manager, then this manager will definitely lose his job. I think he was given enough time and he didn't prove himself even in that enough time so it is very likely that he will fail to prove himself in the next season unless there is a change in his plans.
Yes it's actually true that this might be Eric ten hang last season as the manager of Manchester united if they doesn't improve next season, but sacking him now, next season ending or during the cause of the season wouldn't change anything if the major cause of the problem isn't solve, their has been no major improvement from Manchester united since sir Alex Ferguson left the club.
Let's look at the type of top quality Manager's that has managed Manchester united since sir Alex Ferguson left the club till date, jose Mourinho, Luis van gaal and ole gunnar solskjaer, I believe that those names I made mentioned did pretty well, and they would have done more better, if the working environment of Manchester united was very much conducive.
Luis van gaal even said it that the hierarchy of Manchester united pays less attention to what's going on on the pitch, and focus more on commercial activities, he said that Manchester united is a commercial club, so till that changes, regardless of who is in charge, Manchester united will keep on struggling just as this immediate past season.
