Louis van Gaal will delay his decision over whether to sign Radamel Falcao because of concerns about the Colombian's injury record.
Falcao arrived at Old Trafford on deadline day on loan, with a view to make the move permanent for a fee of around £43 million at the end of the current campaign.
However it's not been plain sailing so far and the former Atletico Madrid hitman has scored just one Premier League goal, and hasn't played since mid-October because of a calf injury. That has thrown his future into doubt with Manchester United now questioning whether to commit such a huge fee for a player who has struggled to make it onto the pitch in recent months.
Of course he also missed the World Cup with a serious knee injury, and it was claimed earlier this month that he is still managing that problem and applying ice to the area after each training session. He's yet to complete a full game for the Red Devils either.
Now the Daily Mail say that Van Gaal is still pondering his options ahead of the summer, and that it's by no means certain that Falcao will be at Manchester United next season. The Dutchman also confirmed his injury worries were behind the reason they opted for a loan deal instead of a permanent transfer.

'Do you think we expected he'd be injured for so many weeks? Because of that (injury setback) maybe we didn't buy him,' the Manchester United manager told reporters.
Falcao's problems have only served to highlight the risk undertaken by Van Gaal to sell Danny Welbeck to Arsenal. The England international joined the Gunners in a deal worth £16 million and compared to his replacement, has hit the ground running at his new club.
Despite that, Van Gaal says he expects his decision to be proved right by the end of the season. 'I hope [to be vindicated]. That is clear, I think.'
He added: 'We have Van Persie and (James) Wilson, and when you keep Welbeck, you don't give any chances to youngsters. That's also our philosophy, to give opportunities to youngsters.
'And then also we could buy Falcao. So (if) that is not enough reason, then I don't know - I'm not a very good manager,' Van Gaal said. 'For him it was a very good decision because as a line-up player he develops himself much more. If it was right for Manchester United is dependable on how they play, how they score and in what position we shall finish in the league.'
Welbeck will go up against his former club when Arsenal take on Manchester United this evening.
