Midfielder, but really you can't say more specifically than that.He likes to play with total freedom and he is granted that at Juve. He's played deep in central midfield, box-to-box and as an attacking midfield. Under Allegri he's mostly played at left midfield. But to go back to your question, no, he's not by any means a typical creative number 10. When he has played in that area, he does a role similar to what Yaya used to for City when played in an advanced role under Mancini.
