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

Boss Ruben Amorim argues that changing Man Utd's tactical system due to external scrutiny would have been "the finish" for him.

Initially against Newcastle, Amorim moved away from his trademark back three setup with wing-backs and chose to field an standard four-man defense shielded by two central midfielders.

Amorim acknowledged this at times became a back six in the final phase as his squad clung on for a win - securing only their second shutout of the season.

While he once notably said that even the highest authority could force him to adjust his system, Amorim maintains the ability to utilize different formations has consistently been part of his strategy.

However, he stresses he could solely alter the tactics when his team were faring at an acceptable level - or else it would look as if he was succumbing to external criticism.

"When I arrived here last season, I realized perhaps I didn't possess the players to excel in a back three, but it was the beginning of a project," he stated.

"We were trying to build an style. Today is a separate time. We don't have a lot of personnel, and we have to adjust, so they understand why we are switching things up.

"It is not because of the pressure of the media, or the faithful.

"Whenever you discuss altering the system repeatedly, I cannot make a change because the players will understand I'm altering things because of external voices and I believe that is the downfall for the coach.

"When we are playing well in our preferred setup, that is the moment to evolve.

"We are going to become a more complete side because when all the players return, we are not intending to use three defenders exclusively."

Availability Issues Persist

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

He is, nonetheless, managing with a injury-ravaged squad, with multiple first-team stars already unavailable for the upcoming home game against struggling Wolves.

That number will increase if midfielder Mason Mount is unable to recover the injury that led to his withdrawal from the Newcastle game at the interval.

Skipper Bruno Fernandes is a key name who will miss the Wolves clash, despite the fact he is reportedly pressing his manager to let him to return after his hamstring problem.

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

Fernandes' Role Is Unwavering

Nevertheless, the Portuguese star will probably still be deeply engaged, as whereas most unavailable stars watch matches from a private box, Fernandes was spotted keeping a close eye on the warm-ups from the entrance of the player's tunnel before the Newcastle game.

Amorim anticipates his captain to continue offering input.

"He is a leader," he affirmed. "He cannot be the type of player that when he is absent, he's not talking and speaking. He's constantly communicating. That is the reason he's the captain.

"He has flaws at times - his mannerisms he moves his arms - but he has a lot of positive qualities. After he recovers, he goes to watch the other guys 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 born leader. The guy is a true captain."

Return Schedule for Key Players

While the exact timeline for the captain's comeback - and that of other unavailable stars like Kobbie Mainoo, Matthijs de Ligt, and Harry Maguire - remains uncertain, by the end of January, United will welcome back Noussair Mazraoui, Amad Diallo, and Bryan Mbeumo from international competition.
