Manchester United striker Will Keane's loan move to Wigan Athletic is threatening to break down after the 20 year old picked up a foot injury while training with the England Under-21's.
Keane missed the 9-0 win over San Marino and after a chequered injury history will undergo tests prior to completing his move to the DW Stadium.
The United forward ruptured his cruciate knee ligament while on England Under-19 duty in June 2012 and missed the whole of last season, and Wigan boss Owen Coyle wants every precaution taken before Keane completes his move to the Championship promotion chasers.
"It is fair to say we have a verbal agreement with Manchester United regarding Will," Coyle said."He was away with the Under-21s this week and took a slight knock, so I spoke to David Moyes.
"Given the lad had a very serious injury we would always be guided by them in terms of when they think it is the right time for him to come out on loan.
"This week would probably be too soon but if the Manchester United doctor is happy with it, there is a possibility we could have that sorted by next week."
Should he complete the move to Wigan, who were relegated from the Premier League last season, Keane will join up with fellow United loanee Nick Powell.
The Stockport-born forward has made just one professional appearance for United, in Premier League defeat to Blackburn Rovers in December 2011 which came six months prior to a knee blow which kept him out for 16 months.
Keane has three caps to his name for the England Under-21's and Coyle is tipping him to become a "top player."
"This is a lad who is going to be a top player," said Coyle. "He knows where the goal is and plays beyond his years in terms of his knowledge of the game.
"He is a player I have admired for many years. It would be great to add someone of that quality to the squad.
"David Moyes will keep me up to speed with that and we will see how that one pans out in the next couple of days."
