The Italy international remains optimistic that his team-mate could stay at the San Paolo amid ongoing speculation linking him with a big-money move
The Uruguay international recently voiced his frustration with Napoli's €63 million asking price following Aurelio De Laurentiis' comments that interested clubs will have to meet his buy-out clause and demanded face-to-face talks with the club president once he returns from his holiday after the Confederations Cup.
Nevertheless, Maggio is refusing to give up on the prolific attacker and wants Cavani to stay put.
"We have not spoken to each other recently. There has simply not been any time. But we will have a calm and relaxed talk about his situation," Maggio told La Gazzetta dello Sport.
"I don't know yet when we will meet, but we have always had a good relationship. I will try to convince him to stay put. It's then up to him to make a decision, but I obviously want him to stay at Napoli."
The 26-year-old Cavani's current Napoli deal is due to expire in the summer of 2017.
