It's unlikely to happen. PSG has been threatening him to be unplayed for this season. PSG will be putting him on the bench this season. That's why PSG is looking for a new striker. PSG still hopes mbappe leaves from the club.
Just because PSG is looking for a new striker and it doesn't mean mbappe will be moving to the real madrid. There's no talk between PSG and madrid.

I think that mbappe must accept it if he gonna be benched by the club instead of given chances to play next season. PSG is not having a lot of choice. Mbappe is still trying to stay even longer in the club no matter what kind of sanction will be given by PSG.

Madrid can't afford very big amounts of money to buy him before the club sells some players first.
