Rodrigues says they've opened talks over a new contract.
"The club's managing committee has already decided, we intend to extend his [Neymar's] contract beyond 2014, we are working to make that happen," Rodrigues told UOL.
"We have already opened talks with Neymar's father, who denies there is any kind of agreement [with Barcelona] and we believe him. He said Neymar will be where he is happy.
"The news from Daniel Alves isn't anything new, Neymar is being sold every day, there is always news that he has been sold.
