Chelsea boss Maurizio Sarri has taken the blame for the injury suffered by N'Golo Kante in their win over Watford.

Kante was forced off with a hamstring injury.

Sarri confirmed: "The problem is with his hamstring. But I think I made a mistake, because probably today he had to rest. Sometimes it's very difficult to put on the bench a player so important, like Hazard, like Kante, but you have to do it, otherwise you risk, and I have to say I made a mistake.

"I think it's very difficult to recover him for the next two matches. We want to play the final, so he's lucky, and we have to try to recover him for the final in case."
