Manchester United legend Bryan Robson is confident Radamel Falcao will prove his class.

The Colombia forward has struggled for form since sealing a shock season-long loan move from Monaco to United on the final day of the summer transfer window.

"When he first came in he really did do well and he looked a real player but unfortunately he has picked up this injury and he's been out for quite a time but on the training pitch you can see the quality that he's got," Robson told talkSPORT.

"I'm sure he will be a big player for Manchester United when it really matters."
