The new Chelsea boss is settling into life in west London after a drawn out process before his eventual appointment.
Sarri has already brought Jorginho in from former club Napoli.
And the Blues have been linked with the likes of Kalidou Koulibaly and Elseid Hysaj, who played under the 59-year-old at the San Paolo Stadium.
But De Laurentiis has lashed out at Sarri, accusing the Chelsea chief of trying to ‘dismantle’ his Serie A side.
“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 move Hamsik deeper.”
Chelsea have also been linked with moves for Juventus duo Gonzalo Higuain and Daniele Rugani.
