Mbappé sent a letter to PSG last month stating that he had no intention of extending his contract, which expires in 2024.

But he later clarified that he had not asked the French club to allow him to move to Spanish giants Real Madrid, who have in the past tried and failed to land the World Cup-winning forward.

PSG face the dilemma of allowing Mbappé to run down the final year of his contract and being unable to recoup any of the €180 million ($195.7m) they spent in 2017 to sign him from AS Monaco.

"My position is very clear. I don't want to repeat it every time: if Kylian wants to stay, we want him to stay. But he needs to sign a new contract," Al-Khelaifi told reporters after unveiling Luis Enrique as the club's new manager.

"We don't want to lose the best player in the world for free, we can't do that. This is a French club.

"He said he would never leave for free. If he changes his mind today, it's not my fault. We don't want to lose the best player in the world for free, that's very clear."

Nasser Al Khelaifi: "Kylian Mbappé he has to decide next week or in two weeks. No more than this".

"If he does not want to sign a new contract, the door is OPEN".
