I don't subscribe to the Kante criticism. Kante is an average, at best, player -- although a machine when it comes to winning the ball back -- therefore I wouldn't be trying to find his best position, I'd look to build the squad around better players. He's at his best in a two; anything else and he struggles. There are solutions, but I wouldn't change my whole system for him.
I think there's something wrong with that Chelsea squad. How many times are they going to 'down tools'? I thought it was Mourinho third-season-syndrome, but then they down tools under Conte, and now I feel like they're doing it again.
They need to stick with a manager and rebuild. I'm not sure Sarri is the one, because he's too idealistic.
