The Brazil international has been heavily linked in the media with a possible move to Real Madrid this summer, just a year after leaving their bitter rivals Barcelona for France in a world-record transfer.
However, Al-Khelaifi is confident the 26-year-old striker will be a Parc des Princes fixture for the foreseeable future.
Asked whether Neymar will be at PSG next season, Al-Khelaifi said in quotes reported by Le Parisien: “For me, for Neymar, I am 2,000 per cent sure he will stay.
“He wants to stay here, he has a contract.
“The Spanish media have been talking since October. He is not happy, this, that…All that is wrong. I don’t respond to rumours.
“I’m sure he’ll stay, he’s a Paris St Germain player.”
Neymar joined PSG in a £200.8m transfer last August and scored 28 goals in all competitions before suffering a broken metatarsal in February which has kept him sidelined since.
