Man Utd boss Amorim will be without Mainoo and Martinez against Arsenal.
Man United faced a big blow against Everton after seeing Kobbie Mainoo pick up a yellow card in the 49th minute.
The English midfielder lost possession in his half and had to bring down the opposition player to stop him from scoring.
As a result of his booking, Mainoo has now picked up his fifth booking of the 2024/25 Premier League campaign.
He will now have to serve out a one-game suspension and miss the clash against Arsenal on Wednesday (4 December).
Martinez also got booked for a rough challenge on Beto that could have led to a red card. That was his fifth yellow of the campaign, meaning he’ll miss the Arsenal game too.
