Time is optimal to alter Manchester United's tactical setup - Amorim declares.

Head coach Ruben Amorim says that changing Man Utd's formation due to external scrutiny would have been "the finish" for him.

For the first time against Newcastle United, Amorim abandoned his customary back three formation with wing-backs and chose to deploy an standard back four shielded by two holding midfielders.

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

Although he once notably remarked that even the Pope could pressure him to tweak his system, Amorim maintains the capacity to play with alternative setups has consistently been part of his strategy.

Nevertheless, he clarifies he could solely alter the tactics when his team were doing sufficiently well - otherwise it would appear as if he was bowing to external criticism.

"When I arrived here last season, I realized perhaps I lacked the personnel to excel in a back three, but it was the commencement of a process," he stated.

"We were trying to build an style. Now is a different moment. We are missing a full complement of players, and we have to adapt, so they see the reason we are making changes.

"This isn't because of the influence of you guys, or the supporters.

"When media criticize altering the formation repeatedly, I can't make a change because the squad will believe I'm changing because of you and I think that is the downfall for the manager.

"Once we are performing strongly in our preferred setup, that is the right time to change.

"We will grow into a better side because when all the personnel return, we are not going to play with three defenders all the time."

Availability Challenges Continue

Having just two victories in their last eight outings prior to beating Newcastle, it is questionable whether Amorim is correct to claim his side have been in good form.

He is, nonetheless, operating with a depleted squad, with seven senior players already ruled out for the upcoming 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 among those who will be absent for the Wolves clash, despite the fact he is reportedly urging his manager to allow him to make a comeback following his hamstring injury.

"Fernandes is already saying he has to practice," said Amorim. "However there is no chance he is going to feature against Wolves. No chance. You can write that."

The Captain's Role Endures

However, the Portuguese star will likely still be a prominent presence, as whereas most injured players watch matches from the stands, Fernandes was spotted keeping a close eye on the pre-match routines from the mouth of the player's tunnel before the Newcastle game.

Amorim anticipates his leader to continue offering input.

"The guy is a leader," he stated. "He must not be the type of player that when he is not playing, he's silent and offering advice. He's constantly vocal. That's why he's the captain.

"He has bad things at times - the way he moves his arms - but he has a multitude of positive qualities. Even after he finishes treatment, he heads to observe the rest of the squad practicing. There are a lot of things you don't see.

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

Recovery Timeline for Key Personnel

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