I agree with you. There are rumors that Mbappe will not be in Ligue 1. And many say that Mbappe will join Real Madrid. However, Mbappe has yet to officially say that he will not renew his contract with PSG. Mbappe is likely to renew his contract with PSG. Because in the past few seasons we have heard various rumors that Mbappe will not extend his contract with PSG. He will play in Premier League or La Liga. But each time PSG management made tempting offers to Mbappe and Mbappe renewed his contract. This time is likely to see the same thing.
Real Madrid will submit their final offer in January and will give Mbappe until the middle of the month to agree to the offer and make contract agreement. If this fails then the offer that Real Madrid has submitted will mean it has failed twice.
In the previous transfer window, Real Madrid also offered quite large amount of money to transfer Mbappe, but PSG rejected it and currently the offer is being made directly by Mbappe, not through PSG because Mbappe contract will expire next summer.
It just that it looks like Real Madrid will also enter the Premier League if they fail to get Mbappe, because Haaland is the second option.
PSG is currently at the top with 33 points and if Mbappe really leaves, it is certain that PSG will suffer setback because their main player, Mbappe, who always scores winning goals is no longer with them.
