Radamel Falcao must wait until season's end before learning if Manchester United will sign him permanently.

The Guardian says the loan striker has struggled for form since moving to Old Trafford on transfer deadline day last summer.

United have a £43.2m permanent option on Falcao but reports from France suggest Louis van Gaal has already decided to ditch him.

But United will delay a decision until the end of the campaign and the Colombian is playing for his future.
