Kanté is not a "proper DM". There is a proper DM playing right behind him, his name is Matic. Kanté plays the disruptor role, he chases the ball, but is not disciplined to sit and protect his back four... he's even worse than Herrera at that.
What I'm telling you is not an opinion, by the way. When the season started Conte played Kanté as the DM and moved Matic further up to harness his playmaking/passing skills. The move backfired as Kanté would chase the ball and go AWOL leaving the defence unprotected. Within 5-6 matches (if memory serves me) Conte switched it around making Matic sit back to protect the defence while Kanté does the harassing.
That's why I said, I know you haven't watched Chelsea
