Last year, Neymar signed a contract extension with Barcelona through 2021, with his buyout clause increasing to the current 222 million euros and 250 million ($288 million) by 2018. The bonus Barcelona is now trying to protect is from that deal.

If PSG does sign Neymar, the cost of the transfer would more than double the 105 million euros (then $116 million) that Manchester United paid a year ago for France midfielder Paul Pogba.

PSG starts its season on Saturday, while Barcelona has until Aug. 13.

Two weeks ago, Barcelona president Josep Bartomeu told The AP that Neymar “is not on the market.” He then told ESPN that if Neymar “wants to go then they will have to pay the clause, right down to the last euro.”
