No debate about the RB now. The shame of it is that this development could and should have happened over a season ago. He just needed game time to get himself sorted out in this position in a blue shirt - a position that he'd always nailed down elsewhere. The reason for the delay is that it's only this season that Moyes has seriously looked at using both flanks to attack down.
It might have happened last season were it not for him getting hacked and injured in that pre-season 'friendly'.
