Napoli are keen on bringing Cavani back to the Serie A, but his wage demands is a stumbling block, and De Laurentiis has implored him to take a pay cut.
The former Napoli forward left for PSG in 2013, where he has won 16 trophies, including four Ligue 1 titles.
Cavani has been linked with a return, but his wage demand will have to be reduced for any deal to go through.
“I know you’d all like him, but I can clear this up immediately,” De Laurentiis added. “Edi earns €20m every 10 months. Having him and not letting the others play, at a time when our coach has just taken charge, would be a serious problem.
“Having only one player isn’t enough to win: we had Higuain, who broke the [goal scoring] record with us to earn double.
“We’re making assists, those who work with us break records and go on to earn double.
“Cavani has my number. If he wants, he can call me, lower his salary and put me in touch with PSG. I know he’d like to come back, but he had no qualms about leaving to earn three times more.”
