Speaking after Sunday’s defeat at Anfield, Solskjaer told Sky Sports: “He’s suffered a bad injury, it’s a stress fracture.

“It happened against Wolverhampton and it is not something that has happened before. I’m looking at Marcus to be out for a while. He won’t be back, I’m not a doctor so I don’t know exactly, but we are looking at several weeks and then some rehab after that probably.

“We’ve had many injuries to big players this season, it’s just an unfortunate position that we are in. The window is open and it might be that we look at something for the short term.”
