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

Boss Ruben Amorim says that changing Manchester United's tactical system due to external pressure would have been "the end" for him.

Initially against Newcastle, Amorim ditched his customary three-at-the-back setup with wide defenders and instead use an traditional four-man defense with two central midfielders.

Amorim acknowledged this at times became a six-man defensive block in the closing minutes as his squad clung on for a win - securing just their second-ever clean sheet of the season.

While he once memorably stated that even the highest authority could pressure him to change his system, Amorim insists the ability to utilize different formations has always been part of his long-term vision.

However, he emphasizes he could only make the switch when his team were faring sufficiently well - otherwise it would look as if he was giving in to external pressure.

"When I arrived here last season, I understood perhaps I don't have the personnel to play well in that formation, but it was the beginning of a journey," he commented.

"Our aim was to build an philosophy. Now is a distinct juncture. We don't have a full complement of players, and we have to adapt, so they understand why we are switching things up.

"It is not because of the demands of you guys, or the supporters.

"When the press talk about changing the system all the time, 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 end for the coach.

"When we are getting results in our system, then is the opportunity to adapt.

"We are going to develop into a better squad because when all the players return, we are not planning to use a back three in every match."

Availability Challenges Loom Large

Having just two victories in eight games prior to defeating Newcastle, it is questionable whether Amorim is right to claim his side have been in good form.

He is, however, operating with a severely stretched roster, with seven first-team stars already unavailable for the forthcoming fixture against struggling Wolves.

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

Skipper Bruno Fernandes is a key name who will be absent for the Wolves match, even though he is understood to be urging his manager to allow him to return after his hamstring injury.

"Fernandes is already insisting he has to train," revealed Amorim. "But there is no chance he is going to play against Wolves. No chance. You can write that."

The Captain's Influence Is Unwavering

However, the 31-year-old will almost certainly still be deeply engaged, as while most injured players watch matches from the stands, Fernandes was observed monitoring the warm-ups from the entrance of the player's tunnel before the Newcastle game.

Amorim is sure his captain to continue offering guidance.

"He is a leader," he stated. "He must not be that guy that when he is absent, he's not talking and offering advice. He's always speaking. That is the reason he's the captain.

"He has negative aspects sometimes - his mannerisms he gesticulates - but he has a multitude of good things. Even after he finishes treatment, he heads to watch the other guys training. There are a lot of aspects you don't see.

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

Recovery Timeline for Injured Personnel

Although the exact date for Fernandes' comeback - and that of fellow unavailable stars like Kobbie Mainoo, Matthijs de Ligt, and Harry Maguire - remains unknown, by the end of January, the club will welcome back Noussair Mazraoui, Amad Diallo, and Bryan Mbeumo from international competition.
