The high confidence proves that he can still be in control so that no matter how bad his performance is, he will still be at Manchester United for several reasons, especially the management's trust in this coach seems to be very large even though it looks like a ridiculousness in the end.

Losing to Tottenham should make them realise that there are still many things to improve and Manchester United should not be too forceful to keep Ten Hag because these 3 seasons he has been at Manchester United we must be aware that his performance is quite stagnant.
Although in the end changing the coach will look risky, it could be the right choice when there is a coach who is more suitable to provide direction than Ten Hag then why not do it.
