Time is optimal to change Man Utd's tactical setup - Amorim states.

Manager Ruben Amorim argues that changing Man Utd's tactical system due to media scrutiny would have meant "the end" for him.

In a first against Newcastle, Amorim moved away from his trademark three-at-the-back setup with wing-backs and chose to use an standard four-man defense shielded by two central midfielders.

He himself conceded this at times transformed into a back six in the final minutes as his squad dug in for a win - securing just their second shutout of the season.

Although he once memorably stated that even the Pope could pressure him to change his system, Amorim maintains the capacity to experiment with different formations has always been part of his plan.

Yet, he clarifies he could only make the switch when his team were faring sufficiently well - otherwise it would appear as if he was bowing to outside pressure.

"When I came here last season, I understood maybe I don't have the personnel to perform effectively in that formation, but it was the beginning of a process," he said.

"The goal was to build an style. Today is a separate time. We are missing a full complement of players, and we need adapt, so they understand why we are making changes.

"This isn't because of the influence of journalists, or the faithful.

"When the press discuss altering the formation constantly, I can't make a change because the squad will understand I'm altering things because of you and I believe that is a disaster for the coach.

"Once we are performing strongly in our system, that becomes the opportunity to change.

"We will become a more complete team because when all the personnel are available, we are not going to use three defenders exclusively."

Squad Issues Persist

With only two victories in their last eight outings before beating Newcastle, it is questionable whether Amorim is right to state his side have been playing well.

He is, nonetheless, managing with a severely stretched roster, with multiple first-team players already confirmed absent for the upcoming home game against struggling Wolverhampton Wanderers.

That total will grow if midfielder Mason Mount fails to shake off the knock that led to his withdrawal from the Newcastle game at the interval.

Captain Bruno Fernandes is one of those who will miss the Wolves match, despite the fact he is understood to be pressing his manager to let him to make a comeback after his hamstring injury.

"Bruno is already telling me he needs to train," revealed Amorim. "However there is absolutely no possibility he is going to feature against Wolves. Definitely not. You can write that."

Fernandes' Role Remains

However, the Portuguese star will almost certainly continue to be deeply engaged, as whereas most unavailable players view matches from the stands, Fernandes was spotted keeping a close eye on the pre-match routines from the entrance of the player's tunnel before the Newcastle game.

Amorim expects his leader to continue offering insight.

"He is a leader," he stated. "He cannot be the type of player that when he is absent, he's silent and speaking. He's constantly speaking. That's why he's the captain.

"He has bad things sometimes - his mannerisms he gesticulates - but he has a lot of positive qualities. After he recovers, he goes to observe the other guys 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 leader. He is a true captain."

Recovery Timeline for Key Players

While the exact date for the captain's comeback - and that of fellow unavailable stars like Kobbie Mainoo, Matthijs de Ligt, and Harry Maguire - remains uncertain, before the conclusion of January, United will welcome back Noussair Mazraoui, Amad Diallo, and Bryan Mbeumo from international duty.
