Now is right to change Man Utd's formation - the manager declares.

Manager Ruben Amorim says that changing Manchester United's tactical system due to external noise would have meant "the end" for him.

In a first against Newcastle, Amorim moved away from his usual back three formation with wide defenders and instead deploy an traditional back four with two central midfielders.

He himself conceded this at times transformed into a six-man defensive block in the final phase as his squad clung on for a win - securing just their second clean sheet of the campaign.

While he once notably stated that even the highest authority could force him to tweak his system, Amorim asserts the capacity to utilize varied setups has remained part of his strategy.

Yet, he emphasizes he could only alter the tactics when his team were performing at an acceptable level - otherwise it would look as if he was giving in to outside noise.

"When I arrived here last season, I recognized maybe I don't have the personnel to excel in that formation, but it was the start of a process," he stated.

"We were trying to establish an identity. Currently is a separate juncture. We don't have a full complement of players, and we need be flexible, so they comprehend why we are switching things up.

"It is not because of the demands of the media, or the fans.

"Whenever you talk about changing the system all the time, I cannot change because the squad will believe I'm altering things because of you and I believe that is the end for the coach.

"Only when we are getting results in our preferred setup, that becomes the opportunity to adapt.

"We are going to develop into a stronger squad because when all the personnel are available, we are not planning to employ a back three exclusively."

Squad Crisis Persist

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

He is, nonetheless, managing with a severely stretched squad, with multiple senior players already confirmed absent for the forthcoming fixture against winless Wolves.

That figure will rise if playmaker Mason Mount is unable to recover the knock that forced his withdrawal from the Newcastle game at half-time.

Skipper Bruno Fernandes is among those who will miss the Wolves match, despite the fact he is reportedly pressing his manager to allow him to make a comeback following his muscle problem.

"Fernandes is already saying he needs to train," said Amorim. "However there is no chance he is going to feature against Wolves. No chance. That's definitive."

The Captain's Leadership Endures

Nevertheless, the 31-year-old will likely continue to be deeply engaged, as while most injured players view matches from a private box, Fernandes was observed monitoring the warm-ups from the entrance of the tunnel before the Newcastle game.

Amorim anticipates his captain to carry on offering input.

"He is a leader," he stated. "He must not be the type of player that when he is not playing, he's silent and offering advice. He's constantly speaking. That is the reason he's the skipper.

"He has flaws sometimes - the way he moves his arms - but he has a multitude of strengths. Even after he finishes treatment, he heads to observe the other guys training. There are a lot of things that go unnoticed.

"I don't know if he desires my position or not, but he's a born leader. He is a true captain."

Return Timeline for Injured Personnel

Although the specific timeline for the captain's return - and that of fellow unavailable stars like Kobbie Mainoo, Matthijs de Ligt, and Harry Maguire - is unknown, before the conclusion of January, United will welcome back Noussair Mazraoui, Amad Diallo, and Bryan Mbeumo from international duty.
