Kante has three times more skills than Jorginho to play in the middle. He's got impeccable awareness of position. He can read the flow odd the game more than any other player in the team. He can win balls. He can run with the ball. He can chase down any player in the PL.
Kante is already playing in the middle, doubling up as a defensive cover for Jorginho. Playing there without the added role of right sided AM would be child's play for Kante.
You spent so much time ridiculing Matic as a donkey. When did he become the player without which Kante could not play in the middle?
