Now is optimal to alter Manchester United's tactical setup - Amorim states.

Head coach Ruben Amorim says that switching Manchester United's tactical system due to public scrutiny would have been "the end" for him.

In a first against Newcastle United, Amorim moved away from his usual three-at-the-back formation with wide defenders and instead use an orthodox four-man defense shielded by two defensive midfielders.

Amorim acknowledged this ultimately transformed into a back six in the final minutes as his squad dug in for a crucial result - securing just their second shutout of the season.

While he once famously remarked that not even the highest authority could compel him to tweak his approach, Amorim maintains the option to utilize varied formations has remained part of his plan.

Nevertheless, he emphasizes he could solely alter the tactics when his team were doing well enough - or else it would look as if he was succumbing to external noise.

"When I arrived here the previous campaign, I realized perhaps I don't have the players to perform effectively in that formation, but it was the beginning of a journey," he stated.

"The goal was to forge an identity. Now is a different moment. We lack a lot of personnel, and we need adapt, so they see the reason we are switching things up.

"This isn't because of the pressure of you guys, or the fans.

"Whenever the press criticize altering the system constantly, I cannot make a change because the squad will believe I'm altering things because of you and I believe that is the end for the manager.

"When we are getting results in our system, then is the right time to change.

"We are going to become a more complete side because when our full complement of players are available, we are not planning to use three defenders exclusively."

Squad Issues Loom Large

Having just two wins in their last eight outings prior to defeating Newcastle, it is arguable whether Amorim is correct to claim his side have been playing well.

He is, nonetheless, operating with a injury-ravaged roster, with seven senior players already confirmed absent for the forthcoming fixture against winless Wolverhampton Wanderers.

That total will rise if midfielder Mason Mount is unable to recover the injury that forced his exit from the Newcastle game at the interval.

Captain Bruno Fernandes is one of those who will miss the Wolves match, despite the fact he is understood to be urging his boss to let him to return after his muscle injury.

"Fernandes is already telling me he needs to practice," said Amorim. "But there is absolutely no possibility he is going to feature against Wolves. No way. You can write that."

Fernandes' Leadership Endures

However, the Portuguese star will almost certainly continue to be deeply engaged, as whereas most injured stars view matches from a private box, Fernandes was spotted keeping a close eye on the warm-ups from the entrance of the tunnel before the Newcastle game.

Amorim anticipates his leader to carry on offering guidance.

"The guy is a leader," he affirmed. "He must not be that guy that when he is not playing, he's silent and offering advice. He's always communicating. That's why he's the captain.

"There are bad things at times - his mannerisms he gesticulates - but he has a lot of positive qualities. Even after he finishes treatment, he goes to observe the other guys practicing. There are a many aspects you don't see.

"I'm not sure if he desires my job or not, but he's a born leader. The guy is a leader."

Return Timeline for Injured Personnel

While the specific timeline for Fernandes' return - and that of other injured stars like Kobbie Mainoo, Matthijs de Ligt, and Harry Maguire - remains unknown, by the end of January, United will welcome back Noussair Mazraoui, Amad Diallo, and Bryan Mbeumo from international duty.
