The highly rated forward does not want to see his club end up empty-handed when he eventually makes the move from Brazil to Europe, with his current deal running out in 2014.
The Brazil striker has long been linked with a move away from his current club, with Barcelona, Real Madrid and Bayern Munich all credited with an interest in the player. The 20-year-old has always insisted that he will only move on when the time is right, but he said he wants to ensure his side does not end up empty-handed with him leaving on a free transfer.
"With everything the club has done for me and my family, leaving for free is not an option," Neymar told reporters. "But it's something very distant, and we still have to talk. First I'll try to win some trophies and then I'll think about it. I don't know if I'll be leaving for free.
"It depends on the club and if they want to let me go for nothing."
Meanwhile, his agent, Wagner Ribeiro, has also insisted that Santos will be rewarded when its prize asset eventually makes the move to Europe.
"Neymar's family are very grateful to Santos, the club that built him as a player and projected him to world fame," Ribeiro said. "Certainly at the end of his contract they will study the best way for him to continue in Brazil or go to Europe with Santos benefiting from it somehow.”
