PSG president Nasser Al-Khelaifi said on Saturday he was "2,000 per cent sure" that Neymar will stay at the club for next season.
The world's most expensive player scored twice in a 4-0 rout of Montpellier on his return from a two-match absence through injury.
Spanish media reports earlier this week said 25-year-old Neymar was unhappy in Paris and set to join Real Madrid at the end of the campaign, but Al-Khelaifi rubbished the claims.
"It's a rumour and of course it's not true," said the Qatari.
"He's happy here, he wants to stay here. He only came here five months ago and he still has four and a half years left on his contract.
"The Spaniards want to start a little (game), but we don't want to get into this game.
He won't 100 per cent be with us next season, but 2,000 per cent."
