Harry Maguire will be out of action for 'a few weeks', says Manchester United manager Ole Gunnar Solskjaer, though Luke Shaw could be fit enough to take on Villarreal on Wednesday. 

Both players limped out of United's 1-0 defeat at home to Aston Villa on Saturday lunchtime and United captain Maguire is now set for a period on the treatment table that will also rule him out of England's October international games. 

Shaw has not returned to training yet but Solskjaer is hopeful that the left-back can make it in time of the visit of Unai Emery's men at Old Trafford, with United already missing right-back Aaron Wan-Bissaka due to suspension.

'Luke has been in today, so I'll give him a chance to be involved tomorrow,' Solskjaer said in a press conference ahead of their Champions League tie with Villarreal. 'He didn't train with the team. Harry is more or less definitely out, it doesn't look good. So apart from that, from the bruised pride from the result, we should be ready to go. 

United lost their first Champions League match to Young Boys earlier this month and will be aiming for their first points of the season against a Villarreal side who beat them on penalties in last May's Europa League final. 

Left-back Shaw came off during the first-half of United's defeat to Aston Villa and was replaced by Diogo Dalot, who is expected to replace Wan-Bissaka in the right-back role on Wednesday night. 

United captain Maguire, meanwhile, picked up his injury in the second-half while challenging Danny Ings in the penalty and tried to carry on after picking up the knock, but was eventually substituted for Victor Lindelof. 

Lindelof is now the favourite to replace him at centre-back but Eric Bailly is another option. Phil Jones is unavailable as he was not named in United's 25-man squad for the coming season. 

United were handed a boost this week after Marcus Rashford confirmed he is hoping to receive the green light to start contact training after his shoulder operation.

It was decided after England's Euro 2020 campaign that the 23-year-old would undergo an operation on his shoulder to fix a long-standing problem, with Rashford playing the second-half of last season with the help of injections to help the pain.  

Rashford revealed on Twitter on Monday : 'I see the doctor on Friday for a consultation. All being well, I will get the green (light) to join in with contact training again.'

The United and England star, who took part in light training on Tuesday away from the first-team squad preparing for the Villarreal game, could be in line for his club's first game after the October international break at Leicester City on October 16.  

Amad Diallo was another United player who took part in light training alongside Rashford, with the young forward yet to play this season due to a thigh problem.
