From the news and rumors circulating and I read it states that Nistelrooy has left the Manchester United team and has lost his position in any form because Ruben Amorin did not use the old people who were previous assistant coach and it was stated that Ruben Amorin brought some of his assistants who also previously worked for Sporting.
Whether or not there will be changes related to the composition of the staff or assistant coach to help Ruben Amorin in the future in leading Manchester United but what is clear is that there have not been many official statements regarding all of this.
If Ten Hag brought his ex trained players to Manchester United, now Amorim want to bring his ex assistants to Manchester United. It sounds too much, a good coach not require many thing, look at Maresca and Arne Slot, they didn't ask anything.
Before the announcement I was expecting Ruud to accompany Amorim but now it has been confirmed that Ruud and 2 other former Erik Ten Hag staff are leaving Manchester United. Amorim and Ruud have had discussions and it is possible that there is a disagreement so Amorim prioritizes his staff. I don't mind if the result is better. Amorim already has a lot of plans in place and Ruud concept is not on his radar.
Amorim haven't show anything, it's better if he show his performance with Manchester United first and then see whether his assistants or Manchester United's assistants is better. Manchester United gambling here, if they previously lose coach, this time they will lose coach + assistants.
