I see him more akin to De Jong. For me his main role would be progressing the ball from deep, if he can do that via passing or carrying - I'm agnostic. I also think the higher you play him in midfield, the more his lack of pace gets exposed. He has to learn how to protect the ball and intercept, Jorginho, Matic, Busquets and lots of others were very slow, but they positionally didn't have to cover as much ground, read the game well and knew how to use their body to protect the ball. I don't think he's anything like Iniesta, personally, bar the dribbling. Remember Iniesta wasn't slow when he first broke through, he adapted as he got slower, so it's not really a good player to model him on.
Agreed and we need to decide as a club what his best role is and just stick with it and go balls to the wall developing him in that role, if we want him to be a success here.
