Time is ripe to alter Manchester United's system - Ruben Amorim states.

Boss Ruben Amorim argues that changing Manchester United's tactical system due to public pressure would have signaled "the end" for him.

In a first against Newcastle, Amorim ditched his trademark back three setup with wing-backs and opted to deploy an traditional back four with two central midfielders.

By his own admission this effectively transformed into a six-man defensive block in the latter minutes as his squad held on for a victory - securing only their second shutout of the season.

Despite he once famously said that not even the highest authority could force him to tweak his approach, Amorim insists the capacity to experiment with alternative setups has consistently been part of his strategy.

Nevertheless, he emphasizes he could only alter the tactics when his team were faring well enough - lest it would look as if he was giving in to outside pressure.

"When I arrived here the previous campaign, I recognized maybe I don't have the players to perform effectively in that formation, but it was the beginning of a journey," he said.

"The goal was to forge an identity. Now is a distinct moment. We lack a full complement of personnel, and we need adapt, so they understand the reason we are making changes.

"This isn't because of the demands of the media, or the fans.

"Whenever media talk about altering the system repeatedly, I can't make a change because the squad will understand I'm altering things because of external voices and I think that is the downfall for the manager.

"Only when we are playing well in our preferred setup, then is the right time to change.

"This will help us become a better side because when our full complement of players are back, we are not planning to employ a back three exclusively."

Injury Challenges Persist

With only two victories in eight games before defeating Newcastle, it is arguable whether Amorim is accurate to claim his side have been in good form.

He is, however, managing with a injury-ravaged roster, with multiple senior players already unavailable for the upcoming home game against winless Wolves.

That total will increase if playmaker Mason Mount fails to shake off the knock that forced his exit from the Newcastle game at half-time.

Skipper Bruno Fernandes is a key name who will miss the Wolves clash, despite the fact he is understood to be pushing his boss to allow him to return following his hamstring injury.

"Fernandes is already telling me he needs to practice," said Amorim. "However there is no chance he is going to play against Wolves. No way. That's definitive."

The Captain's Influence Endures

Nevertheless, the 31-year-old will probably still be deeply engaged, as whereas most unavailable players view matches from a private box, Fernandes was seen monitoring the warm-ups from the mouth of the tunnel before the Newcastle game.

Amorim expects his captain to carry on providing insight.

"He is a leader," he declared. "He cannot be that guy that when he is not playing, he's not talking and offering advice. He's constantly speaking. That is the reason he's the skipper.

"He has bad things sometimes - his mannerisms he moves his arms - but he has a lot of positive qualities. After he finishes treatment, he goes to watch the rest of the squad training. There are a lot of things that go unnoticed.

"I'm not sure if he wants my job or not, but he's a born leader. The guy is a leader."

Recovery Schedule for Injured Personnel

While the exact date for Fernandes' comeback - and that of fellow unavailable players like Kobbie Mainoo, Matthijs de Ligt, and Harry Maguire - remains uncertain, by the end of January, the club will see the return of Noussair Mazraoui, Amad Diallo, and Bryan Mbeumo from international competition.
