Mason Greenwood is a doubt to face Crystal Palace on Thursday after being left with a damaged ankle by Oriol Romeu's challenge on Monday, Ole Gunnar Solskjaer says. 

Greenwood was caught late by Romeu in an incident that went unpunished by referee Chris Kavanagh during Manchester United’s 2-2 draw with Southampton at Old Trafford. 

Manager Solskjaer, who was unhappy to see the challenge escape further punishment through a VAR review, now fears the in-form 18-year-old will not be available for the Premier League clash at Selhurst Park. 

Luke Shaw twisted his ankle in the same match and replacement Brandon Williams sustained a head injury, leading to substantial second-half injury time in which Michael Obafemi scored Southampton's equaliser. 

"I'll give Luke as much time as possible – him and Mason, their ankles are swollen and a bit blown up," Solskjaer told MUTV. "I'll give them as much recovery time as possible to give them a chance.  

"Brandon should be fine, he has a gash over the eye but if he can see out of it, then...

"We've not trained obviously this morning [Wednesday] yet but we'll hopefully have two, maybe all three of them."

Solskjaer added of Greenwood, who played on until the 84th minute: "In the heat of the moment, he'll play on and the adrenaline gets you going, and then you get a little bit of reaction after.

"I said after the game that my ankles were a bit weak after many years of football. But obviously Mason carried on and I think it should have been looked upon by the referee, definitely."

Greenwood has played in all seven of United's matches since their campaign restarted on June 19, scoring four goals in his past four starts.

The Saints draw means United are fifth in the table, behind Leicester City on goal difference with three matches remaining.
