Thing is, he isn't playing as a number 10 at the moment, he's playing pretty much as a number 8, which gives him the opportunity to drive forward with the ball, something he is well capable of doing. He brings to the team, pretty much what Doucoure did before his injury, power and mobility to our weak static midfield. At the moment Iwobi is performing better in that role than Doucoure, who has not looked the same player since coming back. In fairness to Iwobi, he's probably also a technically better player than Doucoure.
