Reports emerged in October from RAC1, among others, that the Blaugrana had reached a deal that would see them pay 10 million euros up front with a futher 40 million euro transfer fee either in the summer of 2013 or after the 2014 World Cup.
In an interview with Uruguayan newspaper El Pais, though, Neymar denied that any such arrangement had been made.
"I have no agreement with Barcelona or anyone else," said the 20-year-old Brazil international after winning the newspaper's prestigious "King of South American Football" award, which he collected in Montevideo.
"The only thing I have signed is with Santos, and I'm happy. They're a big club with whom I'm under contract until 2014. The most important thing is to be happy, and I'm with my family. My objective is to help Santos and Brazil, and the best will come with hard work."
