Agreed. But tbf, that's not really been asked of Cabaye.
Though I think he is underrated as a defender.
Controlling midfield has never been asked of our best CM?
In terms of controlling tempo, sure. In terms of physically controlling midfield ala Schweinsteiger (for example, not a comparison), I don't think so. Tiote's often tasked with that responsibility, even given license to push forward in that pursuit.
IMO, Cabaye's best position is still a bit further forward, creating chances, or as a deep-lying playmaker in a 3-man midfield.
