Time is optimal to alter Man Utd's tactical setup - the manager insists.

Boss Ruben Amorim contends that switching Manchester United's formation due to public noise would have meant "his demise" for him.

For the first time against Newcastle United, Amorim abandoned his trademark back three formation with wide defenders and opted to use an standard back four with two central midfielders.

Amorim acknowledged this effectively transformed into a back six in the closing minutes as his squad held on for a crucial result - securing only their second-ever shutout of the campaign.

Despite he once famously remarked that even the Pope could compel him to adjust his approach, Amorim asserts the option to utilize alternative setups has remained part of his strategy.

Nevertheless, he emphasizes he could solely alter the tactics when his team were doing sufficiently well - otherwise it would look as if he was succumbing to external pressure.

"When I arrived here the previous campaign, I realized perhaps I didn't possess the personnel to excel in that system, but it was the commencement of a process," he said.

"The goal was to establish an style. Today is a distinct time. We lack a lot of players, and we have to adapt, so they understand the reason we are switching things up.

"It is not because of the pressure of you guys, or the faithful.

"When media talk about changing the system all the time, I can't make a change because the players will believe I'm changing because of you and I think that is the end for the manager.

"Only when we are playing well in our preferred setup, that becomes the moment to evolve.

"We will grow into a stronger side because when all the personnel are back, we are not going to employ three defenders exclusively."

Squad Crisis Loom Large

With just two wins in eight games prior to beating Newcastle, it is arguable whether Amorim is right to say his side have been in good form.

He is, nonetheless, operating with a depleted squad, with multiple senior stars already ruled out for the forthcoming fixture against winless Wolves.

That figure will grow if playmaker Mason Mount is unable to shake off the injury that led to his exit from the Newcastle game at the interval.

Skipper Bruno Fernandes is a key name who will miss the Wolves match, despite the fact he is reportedly pushing his manager to let him to return following his hamstring problem.

"Fernandes is already saying he needs to train," said Amorim. "However there is absolutely no possibility he is going to play against Wolves. Definitely not. You can quote me on that."

The Captain's Role Remains

However, the 31-year-old will likely still be a prominent presence, as whereas most injured stars view matches from the stands, Fernandes was spotted monitoring the warm-ups from the entrance of the player's tunnel before the Newcastle game.

Amorim anticipates his leader to carry on offering guidance.

"He is a leader," he declared. "He must not be that guy that when he is absent, he's not talking and speaking. He's constantly communicating. That's why he's the captain.

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

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

Recovery Schedule for Key Personnel

Although the exact date for Fernandes' comeback - and that of other injured players like Kobbie Mainoo, Matthijs de Ligt, and Harry Maguire - is unclear, by the end of January, the club will see the return of Noussair Mazraoui, Amad Diallo, and Bryan Mbeumo from international duty.
