Time is right to change Man Utd's formation - Amorim insists.

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

In a first against Newcastle, Amorim abandoned his trademark three-at-the-back formation with wide defenders and instead field an orthodox back four with two central midfielders.

By his own admission this ultimately became a six-man defensive block in the closing phase as his team dug in for a crucial result - securing just their second clean sheet of the season.

While he once memorably remarked that even the Pope could pressure him to adjust his approach, Amorim insists the capacity to experiment with alternative setups has always been part of his strategy.

Nevertheless, he clarifies he could solely make the switch when his team were faring at an acceptable level - lest it would look as if he was bowing to external noise.

"At the time I came here the previous campaign, I realized perhaps I lacked the players to play well in a back three, but it was the beginning of a process," he commented.

"Our aim was to establish an philosophy. Currently is a different moment. We lack a full complement of players, and we have to adapt, so they comprehend why we are changing.

"The change isn't because of the demands of the media, or the faithful.

"When you talk about altering the system repeatedly, I can't make a change because the squad will understand I'm changing because of external voices and I think that is the end for the manager.

"When we are playing well in our preferred setup, that becomes the opportunity to adapt.

"This will help us become a more complete team because when our full complement of personnel return, we are not intending to employ three defenders in every match."

Availability Crisis Persist

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

He is, though, operating with a severely stretched squad, with seven senior stars already ruled out for the upcoming fixture against winless Wolves.

That figure will increase if midfielder Mason Mount fails to recover the knock that forced his withdrawal from the Newcastle game at half-time.

Captain Bruno Fernandes is one of those who will be absent for the Wolves match, despite the fact he is understood to be pushing his boss to let him to make a comeback after his muscle problem.

"Fernandes is already saying he has to train," revealed Amorim. "However there is no chance he is going to feature against Wolves. No way. You can quote me on that."

The Captain's Influence Is Unwavering

However, the Portuguese star will likely still be a prominent presence, as whereas most injured players watch matches from the stands, Fernandes was seen keeping a close eye on the warm-ups from the mouth of the tunnel before the Newcastle game.

Amorim is sure his captain to carry on providing insight.

"He is a natural leader," he declared. "He cannot be that guy that when he is not playing, he's not talking and offering advice. He's always communicating. That's why he's the captain.

"There are flaws sometimes - the way he gesticulates - but he has a lot of positive qualities. Even after he recovers, he goes to observe the other guys practicing. There are a many things 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 Players

Although the precise date for Fernandes' return - and that of fellow unavailable stars like Kobbie Mainoo, Matthijs de Ligt, and Harry Maguire - is unknown, by the end of January, United will welcome back Noussair Mazraoui, Amad Diallo, and Bryan Mbeumo from international duty.
