Manchester United forward Mason Mount will be out for “several weeks” with a leg injury, says manager Ruben Amorim.

The England international was forced off just 14 minutes into Sunday’s Manchester derby win at neighbours City.

Speaking after United’s Carabao Cup defeat at Tottenham about Mount’s expected absence, Amorim said: “I don’t know the exact date but it is going to be long.”

Mount was making just his fourth Premier League start of the season. He made only five starts during his first season with United after joining from Chelsea in July 2023.

The 25-year-old missed five months of last season with thigh and calf injuries, and has been out for two months of the current campaign after suffering hamstring and head injuries.

Asked whether Mount is injury prone, Amorim added: “That is not my department.

“What I can do is help Mase to teach him to play our game while he is recovering, to give him that time to think about different things.

“The worst part is that we don’t have time to train as you should do while recovering with a lot of injuries. We are always travelling, we don’t train enough with the team together. It makes it hard to recover for the games.

“We try to manage it with rotation. With Mason Mount, we are going to help him and it is really hard for him to be out so long. He is trying really hard. If they try hard, we will help them to the end.”
