After losing Lionel Messi who did not renew his contract, PSG has potential will loss their star player Mbappe next season after announcing not to renew his contract which will end next season in 2024. Seems difficult for PSG right now, if not sell Mbappe they will loss great opportunity to earn above 100 million euros due Mbappe contract expiry on June 2024. But one side they if want get transfer fees has to sell Mbappe and seems the era or PSG have been over after leaving by Lionel Messi and Mbappe.
Left Neymar not rumor yet will leave PSG or not, he has linked with Manchester United but not official announce yet for Neymar leave PSG because he still injury right now and absent many games with PSG in this season.
If Mbappe and Neymar also leave in the upcoming transfer market, then of course I personally believe PSG's performance will fall and it may be difficult to win the Ligue 1 title. After all, it's only natural that Mbappe is not willing to extend his contract because after all, playing at PSG doesn't make him his career looks better. What's more, the teams that want Mbappe are big clubs and of course, it would be better for Mbappe to try another challenge to play in another league apart from Ligue 1. Because then, of course, Mbappe will have a great chance to continue to develop, and maybe also with many titles that he might get like Haaland for example.
