The former centre-back has told the Italian media that his boyhood club are a more balanced side now the Argentina international is at Paris Saint-Germain
The Argentina international moved to the French capital during pre-season, but the 38-year-old believes that his hometown side are more competitive now than when he was at the club.
“[With Napoli] I see a team that, while last year had the unpredictability of [Ezequiel] Lavezzi, this year is more balanced, more complete," he told Tuttosport.
“I would recommend all players go to Napoli, it is a gratifying and successful place.
“I tried to organise with president [Aurelio] De Laurentiis a tour of Dubai last year, but it didn't happen. I hope to one day return to Italy though and work as a sporting director. And in my hometown would be even better.”
The former Juventus and Parma man also commented on the recent performances of his brother Paolo Cannavaro, who plays for the Partenopei.
“It's not for me to say, but in the last three years, I think he has become one of the best defenders in Italy," he stated.
"Yes, he has committed some errors, but so did [Alessandro] Nesta. I have to credit [Napoli coach Walter] Mazzarri, who has sent him on to the pitch relaxed and confident.”
He concluded the interview by explaining who believes will win Serie A this season: “For the title, I think Juventus. Napoli will always have my heart, and it is normal that I want them to win.”
