Neymar is desperately hoping Ganso decides to remain at Santos, joking that he has been begging his team-mate not to abandon him.
The star pair are on international duty in Europe as Brazil prepare to challenge for Olympic gold at the London Games.
But their absence from domestic competition has not quelled speculation surrounding their respective futures at club level.
While Neymar has claimed there is no chance of him leaving the Vila Belmiro before the next World Cup, he said he has no idea if Ganso will also stay at Santos.
“I have had to repeat for three years that I will stay at Santos,” Neymar was quoted as saying by Lancenet.
“Everyone knows that I will stay at Santos until 2014.
“I may or may not sign a new deal (after that); I will only know that when the time comes.
“But (Ganso) has not told me yet if he is going to leave. If I had to talk not about the friend, but the player, I would say that everyone wants to have someone like him on the team.
“I do not know much about what is happening. I ask him not to abandon me. I hope he will not go far away from me.”
Neymar is widely expected to join Barcelona when his contract with Santos expires in 2014, while Ganso has been heavily linked with both Porto and AC Milan.
