Manchester United manager Ruben Amorim has revealed he has been forced to make changes and put time limits due to workload management amid injury woes to the players. The Portuguese suffered his first defeat as United’s manager in a 2-0 loss against Arsenal at the Emirates Stadium on Wednesday.

Second-half goals from Jurriën Timber and William Saliba, which came from corners, helped the Gunners in securing all three points in the Premier League.

Harry Maguire, Tyrell Malacia, and Mason Mount were all used for less than 60 minutes by Amorim.

“It’s not because I like to change all the time, but we have to have all the squad fit,” Amorim said. “So for example, Harry Maguire has a time limit, Tyrell Malacia has a time limit, Mason Mount has a time limit, Leny Yoro has a real time limit, so we have to manage within games, different methodology, different way of playing, more metres to press.

“Tomorrow we have to assess and the guys that are a little bit of risk to some injury will not play, so we have to have everybody to work, to play and to improve the squad.”

Amorim said it is crucial for them to take the positives out of the match irrespective of the final result.

“I make the evaluation of the game regardless of the result,” he said. “Like I said, after the 4-0 [win against Everton] you can take positive things, but we have to improve and you already knew that.

“But you can feel it in the stadium, especially in the end of the first half you can feel they were not comfortable, you can feel it in the stadium, so you can take that.

“You see a goal and then the momentum changes and it’s really hard for us to take full control of the game but we try it.”

Manchester United will next take on Nottm Forest at Old Trafford on Saturday.
