Manchester United can get all the whole players they want during the transfer window but that won't solve the problem, we can say that Manchester United has been amongst the most active team in Europe during the transfer window, making top signing on different positions but as the season has commenced we haven't seen that pay off.
The issue for Manchester United is the mentality not the money they have to spend. I must say that Ten Hag isn't the man Manchester United needs. The team goes into every season knowing they won't win the league, UCL and at their best they can only hope for the FA Cup. This isn't the mentality that kept Manchester United on top during sir Alex Ferguson era.
I agree with you that Ten Hag is not suitable as Manchester United coach. Moreover, in Ten Hag's third season at Manchester United, the quality of Manchester United game has continued to deteriorate even though Manchester United has spent a lot of money recruiting players that Ten Hag wants. It is time for Manchester United's management to find a replacement for Ten Hag so that Manchester United's performance can improve again and can become a respected club in the fight for the championship title in various competitions as it did during the Sir Alex Ferguson era.
That is so true, normally I would understand some things taking time, because a manager can't just take over a team and win all the games, and if this was the first season ever for him then I would say that's normal and the team is just getting adjusted to how he plays, but right now it's his third season and it's clear that we are not going to see them get any better. If they started terrible but became better, then I would say it was a good decision to keep him, this dude was third place, on his first season, won fa cup on his second season, these are all good, and he ended with a cup every season he has been there.
I think it is clear that ETH is only given a courtesy extended time because they thought he would make the team better but it's clear that he is not getting better at all, he is getting worse and worse. This is why I think he should be fired right away.
