Santos president Luis Alvaro Ribeiro says he'll report Real Madrid to FIFA if it is found that Neymar has a pre-contract with them.
There's claims that Neymar already has an agreement to join Real in January.
But Ribeiro told Sport: "Neymar has nothing signed. First because it is illegal. He has an active contract.
"It would be an illegality on the part of Madrid, I'm sure (Real president) Florentino Perez would not commit, because he could be reported to FIFA for incitement to negotiate a contracted player."
