Neymar has previously indicated he will leave after the 2014 World Cup, but is not planning to leave without Santos receiving a fee for him.
He said: “With everything the club have done for me and my family, leaving for free is not an option.
“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.”
