Is he really a #10 though? Haven't really seen that much of him but to me he has looked more like an attacking CM. Yes he's lightweight, but so are Hendrick and Shelvey, or at least weak, and they are slow as fuck too, so im not sure we're gonna lose out so much defensively.
Having said that, I would rather have seen us sign a two way player who can really dictate the play and tempo of a game. With fucking legs preferably.
