“It’s baffling to have a player like Kante playing in offensive areas where you’ve got other players who can do that.”
The loss leaves Chelsea seven points adrift of Manchester City, leaving Sarri unhappy.
He said: “I am disappointed because we played very badly. I think we played very badly in all directions – physically, mentally, technically and tactically.
“I knew we had some problems and with this performance today it was clear to everybody we have problems to solve. I think in the last three or four matches we have started not really very well. Today I did not like anybody.”
