The owner of the Serie A side has claimed the Sweden international is to depart Parc des Princes this summer due to his unhappiness over the imminent arrival of the Uruguayan
The 31-year-old only arrived in the French capital from AC Milan last summer, but with the Uruguay international believed to be close to joining PSG in a £51.8 million (€60m) deal, the Napoli chief claims Ibrahimovic will seek pastures new after being angered by the prospect of sharing striking duties with another marquee name.
"Ibrahimovic will not play with Cavani, he has been promised a transfer," he told Tutto Napoli.
De Laurentiis then ruled out the prospect of the Sweden international, whose current deal with les Parisiens runs until 2015, moving to Naples, as well as Borussia Dortmund striker Robert Lewandowski.
"Lewandowski will not come, he will go to Bayern or Monaco."
The Partenopei chief then took a swipe at Cavani, suggesting his decision to leave Stadio San Paolo was motivated purely by money.
He added: "Cavani is attached only to the money."
The 26-year-old has been linked with almost every major club in Europe during the summer transfer window, but les Parisiens' financial strength appears to have won the race for his signature.
Earlier in July, PSG boss Laurent Blanc revealed his interest in Cavani, but also insisted that he could play alongside Ibrahimovic.
