We have many midfielders, but we need a dynamic and powerful runner in there with a physical presence that'll allow us to control the midfield more. He's a player that can grab the game by the scruff of the neck with his runs and strength.
Tiote is strong, but he's slow and not capable of playing box to box, neither is he as good as Sissoko as ball player.
He would be our own Diame, but with better passing and decision making imo. Would improve our team immensly (sp?)
