The pair are held in high regard around Europe and will face a fight to keep hold of them, with both Chelsea and Manchester City keen to add them to their star studded ranks (According to reports on Talksport).
The Uruguayan Cavani has scored 41 in 57 league appearances since his move from Palermo in 2010 and has formed a lethal partnership with Lavezzi.
And now president De Laurentiis says it will take 'crazy' money to sign the pair. Ahead of Napoli's Champions League last 16 second leg clash with Chelsea, he said: "We are not using our players for the transfer market.
"Cavani? When he was at Palermo he was good but he was not scoring all these goals. Right now everyone wants Cavani and Lavezzi. If some crazy guy wants to put down £100m then maybe."
