I could go on mate. Why don't you watch the guy play. Everyone's wrong but you.
I could find you numerous articles and sources where he's quoted as being a natural box to box player. He is not a natural DM. He plays box to box. Just because he's supposedly the deepest player in a system doesn't mean he's a defensive midfielder.
Xabi Alonso played deepest for Madrid this season but he's not a defensive midfielder. He's a deep-lying playmaker. Fernandinho is more of a box to box player even though he played deepest for City. Gerrard is a deep-lying playmaker rather than a defensive midfielder for Liverpool.
Please actually watch him in some games before commenting on what type of player he is.
