That’s fine and true but you’re arguing that Traore is actually good.
Barcelona’s aura in world football is not germane to the question of whether Traore was Wolves best or most valuable player which he absolutely was not.
How many Wolves players do you think even current Barcelona would actually want? I can think of Neves and maybe Moutinho, and that's it.
He was their most talented and dangerous player but poorly utilised by the club, that's a view I've always held and expect to be proven correct when he's a roaring success at an elite club.
