He looked far more comfortable being pushed up to be honest. Which I've always felt his close control near the box would be lacking; but it lets Sissoko and Anita be better at their roles as central midfielders in holding/box2box. For me, if we need to take Cabaye off or he's unavailable for selection, his direct repalcement should be Marv and our system shouldn't change.
He'll get some of his long range shots going now that he's further up and I do like that he's not wasting energy trying to tackle or run around and concentrating the majority of his game using his creativity and passing.
