Santos legend Pele claims he will try to prevent Ganso from leaving the club for Serie A League leaders Milan.
Milan have made the 21-year-old Brazil international playmaker a top transfer target this summer.
Earlier this week, Vice-President Adriano Galliani held talks with investment fund Sonda in Milan.
Sonda own a 45 per cent stake in Ganso and will be key to negotiations.
Santos feel they are being outmaneuvered and have warned Milan.
Interviewed by Brazilian radio station Jovem Pan, Pele said: "Ganso and I will have a chat. I know that he is happy here. If it were to depend on me, he would stay for life.
"I believe the situation is similar to that of Neymar [who turned down Chelsea a year ago], and I am confident.
"A brief chat with Neymar was enough to convince him to stay and I also believe that Ganso will understand that it's the best thing for the moment.
"I will talk to him and I am convinced that he will decide to stay."
