Time is ripe to alter Man Utd's tactical setup - Amorim insists.

Manager Ruben Amorim says that switching Manchester United's formation due to external pressure would have meant "the finish" for him.

For the first time against Newcastle, Amorim ditched his usual three-at-the-back setup with wing-backs and chose to deploy an orthodox back four with two holding midfielders.

He himself conceded this ultimately functioned as a back six in the latter minutes as his team dug in for a victory - securing only their second clean sheet of the campaign.

Despite he once memorably stated that even the highest authority could pressure him to change his approach, Amorim insists the option to experiment with varied formations has consistently been part of his plan.

However, he clarifies he could only implement the change when his team were doing sufficiently well - or else it would look as if he was giving in to external noise.

"At the time I came here last season, I recognized maybe I don't have the squad to play well in that system, but it was the commencement of a project," he commented.

"Our aim was to forge an identity. Today is a different moment. We don't have a lot of players, and we must adapt, so they understand the reason we are making changes.

"It is not because of the influence of you guys, or the supporters.

"When you criticize changing the system repeatedly, I cannot make a change because the players will believe I'm changing because of external voices and I believe that is the end for the manager.

"When we are playing well in our preferred setup, then is the right time to evolve.

"This will help us develop into a stronger side because when our full complement of personnel are available, we are not planning to employ three defenders exclusively."

Squad Challenges Continue

Having only two victories in their last eight outings prior to beating Newcastle, it is debatable whether Amorim is accurate to state his team have been in good form.

He is, nonetheless, managing with a severely stretched squad, with seven senior players already ruled out for the upcoming fixture against winless Wolves.

That figure will grow if midfielder Mason Mount fails to recover the knock that led to his withdrawal from the Newcastle game at the interval.

Captain Bruno Fernandes is a key name who will miss the Wolves match, even though he is reportedly urging his manager to let him to return after his hamstring injury.

"Fernandes is already insisting he needs to train," revealed Amorim. "But there is no chance he is going to feature against Wolves. No way. You can quote me on that."

The Captain's Role Endures

Nevertheless, the Portuguese star will almost certainly still be deeply engaged, as while most injured stars watch matches from a private box, Fernandes was observed monitoring the pre-match routines from the entrance of the player's tunnel before the Newcastle game.

Amorim anticipates his captain to continue offering guidance.

"The guy is a natural leader," he declared. "He cannot be the type of player that when he is not playing, he's not talking and offering advice. He's always speaking. That's why he's the captain.

"There are negative aspects sometimes - the way he gesticulates - but he has a lot of good things. Even after he finishes treatment, he heads to watch the other guys training. There are a lot of aspects you don't see.

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

Recovery Schedule for Key Players

Although the specific timeline for the captain's return - and that of fellow unavailable stars like Kobbie Mainoo, Matthijs de Ligt, and Harry Maguire - remains uncertain, by the end of January, the club will welcome back Noussair Mazraoui, Amad Diallo, and Bryan Mbeumo from continental competition.
