Paul Pogba will miss "a few weeks" for Manchester United, Ole Gunnar Solskjaer has confirmed in concerning news ahead of a key month.

World Cup-winning midfielder Pogba returned to United's starting line-up to face Everton at the weekend but lasted just 39 minutes of the 3-3 draw.

The 27-year-old appeared to suffer a thigh injury and was quickly deemed a doubt for Tuesday's FA Cup fifth-round clash with West Ham on Tuesday.

Solskjaer has since revealed the extent of the issue, which could keen Pogba out of a series of big matches.

United play Real Sociedad home and away in the Europa League in February, before visiting Chelsea in the Premier League at the end of the month and Manchester City on March 6.

"It's an injury that will take a few weeks to heal," Solskjaer told MUTV. "He's just started his recovery, working with the medical staff and we'll get him back as soon and safely as we can.

"Of course, Paul has been very important for us and we're not going to take any risks. [It will be] a few weeks, definitely.

"You never want to be injured and, especially, now Paul was really finding his form and enjoying his football. For us, we just have to take as many points and wins as possible, when you lose players.

"We've been very healthy and strong for a long period so we can't moan too much."

Pogba scored winning goals at Burnley and Fulham in January, although United's form has since suffered a little, allowing City to build a five-point gap at the summit with a game in hand.

Meanwhile, Solskjaer suggested that captain Harry Maguire could be given a rest against West Ham, having sat out just two games since the campaign started.

"Of course I think about if he needs a rest, if he physically can keep going and going," said the United boss.

"The nature of a centre-back position is a different position compared to full-backs and wide men or even central midfielders, or any other position on the pitch. The centre-backs are the ones who are protected mostly from the real fatigue because you're working less.

"Then again, he's never injured, Harry. He's never been really badly hurt, touch wood, and hopefully he'll be able to carry on. But I'm not sure if he'll play on Tuesday or not. I've not decided yet."

United have scored 12 goals across their past two games and although Mason Greenwood did not find the net in the 9-0 win over Southampton or the draw with Everton, Solskjaer has been impressed by his recent displays.

Greenwood created two chances – one of which ended in an assist – and had two efforts on target against Southampton, while he also completed three dribbles. Versus Everton he failed to hit the target or supply a key pass, but was again successful with three of his five attempted dribbles.

"Mason was different class [against Everton]. I thought he was the standout performer on the pitch - he just didn't get the goal that his performance deserved," said Solskjaer.

"I think the last few games, if you look at him closely - yeah, I know we scored nine against Southampton - but if you look at his performance, I thought his performance was top.

"He's improved and matured immensely, and he's working with some of the top forwards in the country, of course. He's learning off them, and it's exciting to see that he's come over his blip and is playing really well."

Jesse Lingard has joined West Ham on loan from Manchester United for the rest of the season.

West Ham have reportedly agreed to cover Lingard's wages for the duration of his time at London Stadium and pay a £1.5million fee to United.

The 28-year-old was allowed to leave to find more regular first-team football, having only made three appearances under Ole Gunnar Solskjaer this season.

The striker has agreed a four-and-a-half-year contract with the Eredivisie giants, having previously enjoyed a spell in the Dutch top flight with Utrecht.

West Ham spent a reported £45m to bring Haller to England in July 2019 after he starred for Eintracht Frankfurt in the Bundesliga, scoring 19 goals in all competitions in 2018-19 as part of a formidable forward partnership with Luka Jovic.

However, his time in the Premier League proved largely disappointing, the 26-year-old scoring 14 times in 50 appearances in all competitions.

The Ivory Coast international was usurped by Michail Antonio as first-choice centre-forward under David Moyes and did not start a league match this season until October 31, when Antonio was struggling with injury.

"West Ham United would like to thank Sebastien for his contribution to the club and wish him all the best for his future career," the Hammers said.

According to reports, West Ham are interested in signing Lyon striker Moussa Dembele to bolster their attack, although the former Celtic forward is said to have little interest in a move to London Stadium.
