He can play the deeper role in midfield perfectly well. Especially against teams that want to press his awareness, great first touch and ability to play 1 touch football really helps.
I've always said I prefer him deeper. He isn't going to take Bruno's position as the way we play is too individualistic. He's not really good enough athletically to carry the ball like Bruno can, and he prefers to keep his passing simple and play it closer which is more efficient but with perhaps less risk/creativity. That style of football is ideal for us in a deeper position as we are often a bit loose in midfield, but obviously at the 10 we need Bruno's creativity.
The only thing that was really holding him back last year was his fitness and speed, but that was starting to look a lot better towards the end of the season.
I'd like to see him play alongside Fred in midfield more often.
