Time is right to switch Man Utd's system - Amorim insists.

Head coach Ruben Amorim contends that switching Man Utd's formation due to public pressure would have meant "the end" for him.

In a first against Newcastle United, Amorim ditched his customary three-at-the-back setup with wing-backs and opted to field an orthodox four-man defense with two holding midfielders.

He himself conceded this effectively functioned as a six-man defensive block in the closing stages as his team dug in for a crucial result - securing just their second shutout of the campaign.

While he once memorably remarked that even the highest authority could force him to adjust his approach, Amorim maintains the ability to play with varied formations has remained part of his long-term vision.

Nevertheless, he emphasizes he could solely make the switch when his team were faring at an acceptable level - otherwise it would look as if he was giving in to external criticism.

"When I arrived here the previous campaign, I realized perhaps I lacked the players to play well in that formation, but it was the commencement of a journey," he commented.

"Our aim was to build an identity. Today is a different juncture. We don't have a full complement of personnel, and we have to adjust, so they understand the reason we are switching things up.

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

"When you talk about changing the system all the time, I can't make a change because the players will think I'm changing because of external voices and I think that is a disaster for the coach.

"When we are getting results in our preferred setup, that is the right time to adapt.

"We will develop into a stronger side because when our full complement of personnel are back, we are not intending to play with a back three all the time."

Injury Crisis Loom Large

Having only two wins in eight games prior to beating Newcastle, it is questionable whether Amorim is accurate to claim his side have been playing well.

He is, however, managing with a depleted roster, with multiple first-team stars already confirmed absent for the upcoming fixture against struggling Wolverhampton Wanderers.

That number will rise if midfielder Mason Mount is unable to shake off the injury that led to his exit from the Newcastle game at the interval.

Captain Bruno Fernandes is among those who will be absent for the Wolves clash, even though he is reportedly pushing his boss to allow him to make a comeback following his muscle injury.

"Bruno is already telling me he needs to train," said Amorim. "However there is no chance he is going to feature against Wolves. Definitely not. That's definitive."

The Captain's Influence Is Unwavering

However, the Portuguese star will almost certainly still be heavily involved, as whereas most unavailable players watch matches from a private box, 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 leader to carry on providing guidance.

"The guy is a natural leader," he affirmed. "He must not be that guy that when he is not playing, he's not talking and speaking. He's always speaking. That is the reason he's the captain.

"He has bad things sometimes - his mannerisms he moves his arms - but he has a multitude of good things. After he recovers, he heads to observe the other guys training. There are a many aspects you don't see.

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

Return Timeline for Injured Personnel

While the precise date for Fernandes' return - and that of other unavailable players 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.
