De Laurentiis confirmed that new boss Carlo Ancelotti sanctioned the sale of Jorginho, but also revealed that Sarri was eager to sign a number of other Napoli players following his departure.
"He wanted to take my whole team to England and dismantle it. I had to lay down the law to Marina [Granovskaia, Chelsea director]," De Laurentiis told Sky Sports Italia.
"He wanted Jorginho and I gave him away after I talked to Ancelotti, who told me he was banking a lot on [Amadou] Diawara and that he wanted to play [Marek] Hamsik deeper."
Sarri, who spent three years with Napoli, will take charge of his first competitive match as Chelsea boss on August 5 when they face Manchester City in the Community Shield.
