Now is optimal to alter Manchester United's system - Ruben Amorim declares.

Manager Ruben Amorim contends that switching Manchester United's tactical system due to public noise would have meant "the end" for him.

For the first time against Newcastle, Amorim ditched his customary back three setup with wing-backs and chose to use an orthodox four-man defense with two defensive midfielders.

Amorim acknowledged this effectively became a six-man defensive block in the latter phase as his squad clung on for a win - securing only their second-ever shutout of the season.

Despite he once notably stated that even the Pope could pressure him to tweak his approach, Amorim maintains the capacity to utilize alternative setups has always been part of his long-term vision.

Yet, he clarifies he could solely alter the tactics when his team were faring at an acceptable level - otherwise it would appear as if he was giving in to external pressure.

"When I arrived here last season, I understood perhaps I didn't possess the squad to play well in a back three, but it was the commencement of a process," he said.

"We were trying to build an style. Today is a different time. We lack a full complement of players, and we have to adapt, so they see the reason we are changing.

"It is not because of the demands of journalists, or the faithful.

"When you talk about altering the system constantly, I can't make a change because the players will understand I'm altering things because of external voices and I believe that is the downfall for the coach.

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

"This will help us become a better squad because when all the players return, we are not planning to use three defenders exclusively."

Availability Crisis Continue

Having just two wins in their last eight outings before defeating Newcastle, it is debatable whether Amorim is right to say his team have been in good form.

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

That figure will increase if midfielder Mason Mount fails to recover 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, even though he is reportedly pressing his manager to let him to make a comeback following his hamstring problem.

"Bruno is already saying he has to train," said Amorim. "But there is absolutely no possibility he is going to feature against Wolves. Definitely not. That's definitive."

The Captain's Influence Is Unwavering

Nevertheless, the 31-year-old will probably continue to be a prominent presence, as while most unavailable players watch matches from a private box, Fernandes was spotted keeping a close eye on the pre-match routines from the mouth of the tunnel before the Newcastle game.

Amorim expects his leader to carry on offering input.

"He is a leader," he affirmed. "He cannot be the type of player that when he is not playing, he's silent and offering advice. He's constantly speaking. That's why he's the captain.

"He has bad things at times - his mannerisms he gesticulates - but he has a multitude of strengths. After he recovers, he goes to watch the rest of the squad training. There are a many aspects that go unnoticed.

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

Recovery Timeline for Injured Personnel

While the precise timeline for Fernandes' return - and that of other unavailable stars like Kobbie Mainoo, Matthijs de Ligt, and Harry Maguire - remains uncertain, before the conclusion of January, the club will welcome back Noussair Mazraoui, Amad Diallo, and Bryan Mbeumo from international competition.
