Nasser Al-Khelaifi did not want to reveal the details of the agreement to Kylian Mbappe.
"Kilian is a great football player and also a great person. As he said after the French Super Cup match, he has an agreement with me.
The details will remain between us; I don't want to reveal the agreement. But it exists.
I don't want to talk about money or say what the agreement is about. We have a gentleman's agreement that has nothing to do with money.
It is an agreement between the player, the president, the athletic director, and the coach. It is more than a signed document," the head of PSG said.
He also announced the change in the club's transfer policy.
"We don't need stars. Today, the star is PSG. We need footballers who respect the jersey and the club and give everything for it," Nasser Al-Khelaifi added.
