Mbappe has not signed a new deal with PSG. His current contract will expire in July of next year and he'll be a free agent. PSG is still looking for ways to make him renew but I doubt it would happen even though I don't put anything past Kylian Mbappe. He may decide to renew.
If I'm not mistaken I understand that in this transfer window PSG extended Mbappe's contract until 2025. In the first situation, Mbappe did not agree with the club to extend the duration of the argument, but later when he was given pressure from the club that either he had to leave the club this season or he had to extend the contract with PSG, in that situation, Mbappe extended the contract until 2025. Mbappe considered leaving PSG as a free agent member but if he left the club as a free agent member, PSG would have faced a huge financial loss, so PSG pressured Mbappe to extend his contract to avoid that financial loss. If Mbappé moves to a club while his contract is still in place, the club will certainly receive the transfer fee he leaves.
there are still pros and cons regarding Mbappe contract at PSG because some people believe that Mbappe has actually extended his contract by 1 season until 2025, but I am a little doubtful whether this news is true because I have not been able to confirm the news. but what I know and what I think now is very clear that in the next season or when the transfer market opens in January, Mbappe will leave PSG and if that happens in January, of course the team that will get Mbappe will have to pay a large amount, but if you wait until the contract expires I think the team that will get him will only get him for free.
I see by transfermarkt that no extension had been made until 2025 and I don't know who some time ago made this rumor but there is no definite clarity until now.
Believing rumors sometimes makes us make mistakes because many media or sources spread false rumors with the aim of seeking popularity and for quite sensational content.
Several times I have said to look for sources that can really be trusted so that we can get real and accountable information.
If Mbappe has extended his contract then the transfermarkt will definitely change the status of Mbappe contract and in fact up to now there has not been single update on the contract.
