Time is optimal to change Man Utd's formation - Ruben Amorim declares.

Manager Ruben Amorim contends that changing Man Utd's formation due to external scrutiny would have been "the end" for him.

For the first time against Newcastle, Amorim abandoned his customary back three formation with wide defenders and opted to deploy an orthodox four-man defense shielded by two holding midfielders.

Amorim acknowledged this effectively transformed into a six-man defensive block in the final minutes as his squad held on for a victory - securing just their second clean sheet of the campaign.

While he once famously said that not even the Pope could force him to tweak his system, Amorim asserts the ability to utilize varied setups has always been part of his long-term vision.

Yet, he emphasizes he could solely alter the tactics when his team were faring sufficiently well - lest it would appear as if he was giving in to external noise.

"When I arrived here the previous campaign, I understood perhaps I don't have the players to excel in that system, but it was the beginning of a process," he commented.

"Our aim was to build an style. Today is a separate juncture. We are missing a full complement of players, and we must adjust, so they comprehend why we are switching things up.

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

"Whenever media talk about changing the formation repeatedly, I can't change because the squad will think I'm changing because of you and I believe that is the downfall for the manager.

"Once we are playing well in our system, that is the right time to change.

"This will help us become a better side because when all the players are back, we are not intending to use a back three exclusively."

Squad Crisis Continue

Having just two victories in eight games prior to beating Newcastle, it is debatable whether Amorim is right to state his side have been playing well.

He is, however, working with a injury-ravaged squad, with multiple senior players already ruled out for the upcoming home game against struggling Wolves.

That number will increase if playmaker Mason Mount fails to recover the knock that led to his withdrawal from the Newcastle game at half-time.

Captain Bruno Fernandes is one of those who will miss the Wolves clash, even though he is reportedly pressing his boss to allow him to return after his muscle injury.

"Bruno is already saying he needs to train," said Amorim. "But there is no chance he is going to play against Wolves. No way. That's definitive."

The Captain's Leadership Remains

However, the 31-year-old will likely continue to be a prominent presence, as whereas most injured stars watch matches from the stands, Fernandes was observed monitoring the pre-match routines from the entrance of the tunnel before the Newcastle game.

Amorim expects his captain to continue offering guidance.

"The guy is a leader," he affirmed. "He must not be the type of player that when he is absent, he's not talking and speaking. He's always speaking. That's why he's the skipper.

"He has flaws sometimes - his mannerisms he moves his arms - but he has a lot of good things. Even after he finishes treatment, he heads to observe the rest of the squad practicing. There are a lot of things that go unnoticed.

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

Return Timeline for Injured Players

While the specific timeline for the captain's return - and that of other unavailable stars like Kobbie Mainoo, Matthijs de Ligt, and Harry Maguire - is unknown, before the conclusion of January, the club will see the return of Noussair Mazraoui, Amad Diallo, and Bryan Mbeumo from international duty.
