Napoli president Aurelio De Laurentis has launched another attack on new Chelsea boss Maurizio Sarri.

De Laurentiis has accused Sarri of overworking his players.

“I didn't like it when he said that we both made mistakes, I don't think I made any, " he told Sky Sport Italia.

“I wasn't wrong not to challenge him, even if it would've been most obvious thing.

“He had a contract, so I could've said something because he was acting in an unacceptable manner, going against players he didn't think were very good.

“These players gave him a lot. He massacred them in his fantastic training sessions, but they always responded well.

“After that, he wanted to take my whole team to England and dismantle it. I had to lay down the law to Marina [Granovskaia, Chelsea director].

“He wanted Jorginho and I gave him away after I talked to Ancelotti, who told me he was banking a lot on Diawara and that he wanted to play Hamsik deeper."
