Now is right to alter Man Utd's formation - Ruben Amorim states.

Manager Ruben Amorim says that altering Man Utd's formation due to external scrutiny would have been "the finish" for him.

For the first time against Newcastle United, Amorim ditched his customary three-at-the-back formation with wing-backs and instead deploy an standard back four with two holding midfielders.

By his own admission this ultimately became a back six in the closing stages as his team held on for a victory - securing just their second-ever shutout of the season.

Despite he once notably said that not even the highest authority could pressure him to change his approach, Amorim asserts the capacity to utilize alternative setups has remained part of his long-term vision.

Yet, he emphasizes he could solely make the switch when his team were faring sufficiently well - otherwise it would seem as if he was succumbing to external noise.

"When I arrived here the previous campaign, I recognized maybe I didn't possess the personnel to perform effectively in that system, but it was the commencement of a project," he commented.

"We were trying to build an style. Currently is a different time. We don't have a full complement of personnel, and we have to adjust, so they see the reason we are making changes.

"This isn't because of the demands of you guys, or the fans.

"Whenever you criticize changing the system repeatedly, I can't change because the squad will understand I'm changing because of you and I think that is a disaster for the manager.

"Once we are performing strongly in our system, that is the moment to adapt.

"We will grow into a more complete team because when our full complement of players are back, we are not planning to employ a back three all the time."

Injury Crisis Loom Large

Having only two wins in their last eight outings before beating Newcastle, it is arguable whether Amorim is correct to say his side have been in good form.

He is, however, working with a severely stretched roster, with multiple first-team players already ruled out for the forthcoming home game against winless Wolverhampton Wanderers.

That number will grow if midfielder Mason Mount fails to recover the injury that led to his withdrawal from the Newcastle game at half-time.

Captain Bruno Fernandes is a key name who will be absent for the Wolves clash, despite the fact he is understood to be pressing his boss to let him to return following his hamstring injury.

"Bruno is already telling me he has to train," revealed Amorim. "However there is no chance he is going to feature against Wolves. No chance. That's definitive."

The Captain's Role Remains

However, the 31-year-old will almost certainly continue to be heavily involved, as whereas most unavailable stars view matches from the stands, Fernandes was observed keeping a close eye on the pre-match routines from the entrance of the player's tunnel before the Newcastle game.

Amorim anticipates his captain to continue providing insight.

"The guy is a natural leader," he affirmed. "He must not be that guy that when he is absent, he's not talking and offering advice. He's constantly communicating. That is the reason he's the captain.

"There are bad things at times - his mannerisms he gesticulates - but he has a multitude of positive qualities. After he recovers, he heads to observe the rest of the squad practicing. There are a many aspects you don't see.

"I'm not sure if he wants my job or not, but he's a born leader. The guy is a true captain."

Return Schedule for Injured Players

While the precise timeline for Fernandes' comeback - and that of other injured stars like Kobbie Mainoo, Matthijs de Ligt, and Harry Maguire - is unknown, before the conclusion of January, the club will see the return of Noussair Mazraoui, Amad Diallo, and Bryan Mbeumo from international competition.
