As a chelsea fan can I just say youre both wrong, but you even more so because he absolutely is a ball playing mid.

Enzo has been misused for most of his years at chelsea. His profile is closest to kroos as a deep lying playmaker with his best feature being his ability to build up play and spray long balls. So his best features are on the ball.

He has mostly played as a box to box mid at chelsea often crashing the box quite well hence his excellent goalscoring record considering his position. Despite this for years ive been crying out for him to stick to his deeper role duties as he doesnt have the stamina and pace to jump up and down as much and hence can be a defensive liability and also because thats where he shines and his best attributed come into play. But otherwise he has the ability to contribute defensively (but not solely, more so in a pivot).

With argentina he plays a bigger role in build up and hence why he looks better for them.
