The former Brazil international believes the Partenopei cannot afford to lose their star player but has singled out Leandro Damiao as the perfect replacement if he leavesNapoli legend Careca has urged the Serie A outfit to do everything in their power to hold on to Manchester City and Chelsea target Edinson Cavani.
The Stadio San Paolo side recently turned down an offer from Chelsea for the 26-year-old, while the attacker's mother claimed that he is in talks with both City and Spanish giants Real Madrid over a summer move.
Goal revealed in May that Cavani is part of a six-man shortlist of players City are targeting in a £120m summer splurge - with Fernandinho and Jesus Navas already recruited - while a swap deal involving Edin Dzeko stalled more recently.

"From all the attackers at the Confederations Cup, I like Cavani the most. He has shown over the past three years that he can score all kinds of goals. He is fast, strong, a real beast," the Brazilian told Corriere dello Sport.
"It's quite simple for Napoli, they should not let Cavani go. The team would lose 70 per cent of its strength if he were to leave. He scores too many goals and is always decisive."
The prolific attacker has a €63 million (£53m) release clause in his contract with Napoli, which runs until 2017, and Careca realises that there is a chance Napoli cannot prevent their star player from leaving and advised them to go for Leandro Damiao if Cavani indeed moves on.
"I already alerted Napoli to Damiao some three years ago. There's a lot of talk about him possibly moving to Napoli now. He is a very potent striker who is very clever and has excellent technique."
The 23-year-old Damiao has also been heavily linked with Tottenham and Olympique de Marseille in the past few weeks. His contract with Internacional runs until 2017.
