Santos president Luis Alvaro Ribeiro has warned Real Madrid and Chelsea that he will report them to FIFA over their pursuit of Neymar.
The 19-year-old striker continues to be linked with a move to Europe, with the Spanish giants widely seen as favourites to sign the Brazil international.
Juventus and Manchester City have also shown interest in the highly-rated young forward, although Santos have on a number of occasions stated that he is not for sale.
Ribeiro has, however, previously admitted talks can take place providing Neymar's £40million release clause is met - something which Real and Chelsea are believed to be prepared to do.
However, to add to the confusion, the outspoken Santos president has recently claimed he would do everything possible to stop a deal going through even if the release clause was triggered, and earlier this month claimed he would ask Brazil's president, Dilma Rousseff, for help in providing additional funding to help keep the player at the club.
And speaking to Terra, Ribeiro has warned the likes of Real and Chelsea not to continue with their attempts to try and lure Neymar away from South America.
"If Real Madrid or any other club [that has approached Neymar] decides to meet his buy-out clause, we have no other option but to report them to FIFA for approaching the player without our permission," he claimed.
"Negotiations have been stalled and won't be re-opened.
"Real Madrid spoke with Neymar's management in Paris and made an interesting offer.
"I've told him that we won't let go of him though and he wants to stay with us, too.
"I can assure you that Neymar will play for Santos at the Club World Cup. I have already said it before and that's the way it is."
