As a 6, he has the ability the break the first line of press in a way which Fabinho, Gini and Henderson can't/don't seem to be able to do. Against Villa, he received the ball in very tight spots on several occasions, and while he can feed to the wings like everyone else can, he has very quick footwork and swivelled past the first player on a few occasions which then opened up the pitch for him (and us). Horses for courses, as always, but I do believe he brings something different to our play.
