Manchester United dealt blow as Mainoo injures key player

Mainoo is set to be sidelined for "a few weeks" due to a muscle injury sustained during the 0-0 draw against Aston Villa two weeks ago.

Defender Harry Maguire is also out for a similar length of time having also been injured at Villa Park.

However, fullback Noussair Mazraoui is back in full training after undergoing heart surgery last week.

The Morocco international had a minor procedure and is now training again.
