Actually sacking ten hag, it was stated that nistrooy would be an interim coach and not the manager so it was a clear point that they were going to hire a coach who wasn't going to be him and for the time before the new Manager arrives he's going to manage the team but he did so well a d got some persons including the fans wanting him stay long but the management has already hired another Coach and they may not want to go back on that, even if we aren't hoping amorim fails but if need be, then they can look back to getting nistelrooy that's if hes free by that time because seeing what he has done so far with united, others may want to hire him soon.
Van Nistelrooy played only a few matches, Manchester United's opponents were not the most difficult and it may be hasty to draw conclusions based on these few matches. Moreover, the players' mood may have improved a little because something in the team began to change, expectations of positive changes always have a positive effect on the team. True, van Nistelrooy was originally supposed to be an interim coach, so everything was according to plan.
