I'd say he's a solid, dynamic and technically sound fullback who can also contribute going forward.
Most importantly he's a player who will improve with the right coaching. I remember seeing him at Bordeaux and he looked very average, now he's very much the standout player at Caen - his hometown club.
Caen fans rated him highly until he announced he'd be leaving in the summer.
In a nutshell: he's a good player in poor team.
