I'll have to take your word on that.
He was dodgy for United when he played last season. He's been poor whenever he's played for their U21s. He hasn't played top-level football for 8 months and before that due to his injury he hadn't played in 18 months...
He may prove everyone wrong at Liege, but you would think there would have been a few more high-profile European clubs in for him if any of them thought he was half decent.
