Part of the 20-year-old's playing rights are owned by investment group DIS, who are free to negotiate with parties who are interested in the player.
Speaking after his 200th appearance for Santos, Neymar is adamant that he will decide his own future and that he doesn't intend to leave his current employers any time soon.
"DIS might own a percentage of my rights, as you all know, but they don't decide about my life," Neymar told Lancenet.
"My father and I decide about that. When you hear me or my father saying I'll leave, then you can believe that will happen.
"There are always rumours and I always say that I'll stay. And you keep saying that I'll leave. So, please, at least for once believe my word."
The striker has been linked with moves to La Liga giants Barcelona and Real Madrid.
