It is too early to measure the strength of Ruud van Nistelrooy and also Ruud van Nistelrooy does not have much experience so it is natural that Manchester United does not yet believe in showing Ruud van Nistelrooy as their permanent coach.
I do not think too much of Man United's victory over a team that is not on par with them and indeed the Man United team is a top Premier League team that they should be able to compete in the title race.
And the dismissal of Ten Hag is a step from management to advance or make changes in the Man United team, I welcome this step and hopefully Man United can rise.
Ruud van Nistelrooy also does not want to be a permanent coach and he said that he came to Man United with only one goal, which is to become an assistant. The point is not whether Nistelrooy is capable or not of becoming a Man United coach, but it was a valuable victory that Man United got because it is something they rarely get this season and it can be an encouragement so that they have hope again to rise from their slump.
