Well first he is not an AM or an attacking winger even if his ability may predispose him to those positions, he is more of a deep-lying playmaker, who like to get the ball deep then move it up and dictate the play with his dribbling or his pass.
As for his abilitys his biggest strength is withouts doubts his dribbling, it's surprising how he can past 3 or more players on regular basis even in tight space he is also really fast as well as you probably saw. It could be added that he as some good passing, he is also a hard worker and is really a consistent player.
