I think no other club would have given Mbappe the number of opportunities PSG management has given him. And that's why Mbappe has been interested in joining Madrid every season, but he ended up signing a contract extension with PSG. PSG paid a lot of money for Mbappe. But teams like Madrid or Manchester United are ready to spend this amount of money. But they won't let Mbappe interfere in the club's internal affairs. PSG management, on the other hand, prioritizes Mbappe's opinion on all matters internal to the club. This is why Mbappe is not leaving PSG. It is foolish to think that Mbappe is only at PSG for money.
Most chances in near future we have no chance for Mbappé to join Real Madrid because both parties are happy, and they are doing good job even now this season important for them with having chance of winning Champions League will increase their enjoyment and PSG management will be keep their faith in this system but if they fail to win again then surely things could be change even management can sell this club because we have reports like these few months back with the change of coach and bringing few changes they are having full commitment for the Champions League title and in case of fail we can expect changes and then may be Mbappé will also try to join Real Madrid but now this all will be happened on Real Madrid rules which can cut his salary as well which is he taking from PSG right now.
