Santos says it could report Chelsea to FIFA for allegedly trying to lure striker Neymar without talking to the Brazilian club first.
Santos president Luis Alvaro Ribeiro says Chelsea is insisting on reaching out to Neymar for transfer talks even though the club has already denied an offer made for the 18-year-old striker.
Neymar and his father reportedly met with Chelsea officials after the striker helped Brazil beat the United States in a friendly on Tuesday.
Ribeiro told Brazilian media on Thursday the club may ask FIFA to intervene against Chelsea.
He has said Santos doesn't want to sell the player, but Chelsea can have him by paying the £35 million ($45 million) buyout clause.
Chelsea's initial offer reportedly reached £20 million ($26 million).
