The Brazilian club recently announced that the Spanish side had agreed a first-option deal for the 19-year-old.
However, speaking at a charity match on Thursday, Neymar claimed that no such settlement has been made.
"Not even five months ago I signed a new contract. I have just said I am staying here until 2014 and this has come back," he said.
"I have been sold to different people since I was 10 years old. Now I am on holiday from Santos, Barca and Real Madrid! Now I am just here to play this game."
Real Madrid are also thought to be interested in the Brazilian international.
