Manchester United manager Ole Gunnar Solskjaer has revealed Ander Herrera may have injured himself due to his failure to agree a new deal with the club. The Span international is in the final months of his contract at Old Trafford and has failed to agree a new deal at the club.

According to reports, Manchester United are not willing to pay Herrera’s demand of £ 200,000 per week. The 31 year old who has not played for the club since the 2-1 win over Watford and Solskjaer has suggested that could be down to the contract situation at Old Trafford.

The Spaniard suffered a hamstring injury in United’s 0-0 draw with Liverpool on February 24, then suffered his latest setback in training in the wake of the Watford win.

Herrera is recovering from a thigh problem, but United boss Solskjaer suggested the 29-year-old’s current injury could be related to the ongoing issue of his unresolved future.

Herrera, who joined United from Athletic Bilbao for £30million in 2014, is set to join Paris St Germain as a free agent, after failing to agree terms on a new deal at Old Trafford.

He is understood to want around £200,000-a-week to stay at United, who are said to be offering him in the region of £125,000-a-week, which has led to the impasse in talks.

Solskjaer added: “He’s been working really hard to get fit from his injury he sustained against Liverpool, then he came back and got a different one here in training. “He’s been putting a lot of work in and that’s come at a time when there are contract talks, but that’s ongoing, I can’t really comment too much on how far they are down the line.

“You have to ask him. I don’t know how they’ve been the last few talks, but we’ve let him focus on his fitness as well. “He loves to play and he’s not very happy when he can’t help his team-mates and always gives his all, doesn’t matter if it’s five weeks or five years on his contract.”
