Neymar's adviser, Wagner Ribeiro, revealed PSG made a staggering offer over the summer, which included the use of a private jet and a deal worth €40 million-a-year.
But Curry insists: "He says the father of Neymar used an offer from PSG for an increase at Barca. It's a lie.
"In December 2015, the father of the player and the club found a verbal agreement on a new contract. It concluded in June without any change compared to what was expected.
"Ribeiro has never participated in any negotiations between Barcelona and Neymar. We hired the player in 2011 without him. We renewed the agreement in 2016 without him."
