The Uruguay international’s future has been a source of constant speculation in recent months, with the Blues thought to be lining up a £50m bid for the highly-rated forward.
Real Madrid are also keen on luring the 26-year-old to Spain, and Cavani last week said that he wants to hold face-to-face talks with Napoli president Aurelio De Laurentiis to discuss his future.
Now, Italy international Maggio has waded into the debate by claiming that he will try to convince his team-mate to stay at the Stadio San Paolo.
“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.”
