I don't think it's really a case of his training or his attitude, he's always seemed to have a good attitude to me, he's just incredibly lightweight even if he probably did learn alot more about the defensive side of things by playing wingback a few times.
He did ok in that clip, kept it simple but the pass for the goal and the through ball late on were both excellent. That's not something he ever really showed with us, not enough to warrant him a place as a playmaker anyway, he never seemed to have the pace to play wide, nor the vision to play central.
