I've suggested that the Stats don't tell the full story here so bringing up the stats again is pointless isn't it?
I have watched him quite a bit, in fact i'd say I probably only watch Wolves to watch him play. Have you?
He's often deployed as a wingback in a very defensive team. From that position, creativity may not necessarily result in assists. He, along with Alan Saint Maximin are probably the best dribblers in the league, regardless of other traits like strength and speed.
But Wolves also haven't had great finishers for a while.
You'd have to watch him to appreciate this. When Traore gets going in your final third, there's very little chance of stopping him, and he's a pretty decent crosser as well.
Played in the front three of an attacking team he'll wreak havoc.
