Manchester United manager Ole Gunnar Solskjaer says Paul Pogba "will probably need an operation" on his injured foot.
Solskjaer revealed after Wednesday night's 2-0 defeat to Arsenal, that Pogba's ankle injury may require surgery.
Pogba's future at the Premier League club remains up in the air but United manager was adamant the World Cup winner will stay at Old Trafford despite his latest injury setback.
Solskjaer said: "Yeah I do (expect him to stay). He's injured now and will probably need an operation on his injured foot. So let's see how long it takes for him to get back.
"It's a big blow for us."
Asked when Pogba was expected to return, Solskjaer said: "Three or four weeks maybe, I don't know.
"He's been advised to have an operation by his people and he'll probably do that."
"It's been advised that he'll do it as soon as [possible]. We look after our players' health and are not gonna take any risk with any players that don't feel able to play on."
"We've had scans and it's nothing major. It's something that has to be sorted and dealt with within a time frame and he's been advised to do it as soon as [possible] and he'll probably do it as soon as.
"So he'll be out for three or four weeks probably. We've had consultants looking at him as well and the club has been looking at it, the scans have been done by us. We've been without him all season, so the boys who've been playing have been fantastic."
Solskjær is already without Scott McTominay for “a few months” due to a knee injury so he is set to do some business in the January window.
"Of course it is playing on our decision-making when you have got two players out.
"If it’s possible we will do something. We are looking at one or two."
