Neymar is expected to move to Real in January about the Club World Cup.
"I feel very flattered by them, but at the moment I have made the decision to keep playing in Brazil," Neymar told AS.
"I have nothing decided [about a move to Europe]. What is clear is that, after the end of the transfer window, I will keep playing in Brazil.
"At Santos I have the guarantee I am with my family. There, I am happy and I have my friends. I look at many things with my heart and I decided this it was not the moment to leave."
