Personally , I no longer believe in Mbappe drama transfer to Real Madrid , simply because France and PSG won't let him go and by the time they let him go , Real most likely will already have another top striker in their team. Remember that Real wants the best talent as long as they are still young and Mbappe might be 26 years old or maybe even 27 by the time he can transfer to Real.
PSG are in an awkward situation actually. They want to keep Mbappe with them or simply let him go with an awesome reward rather than seeing him walk for free next season.
It is known that PSG is pushing for an extension of contract with Mbappe, but it is clear that he will not do that since he counts on joining Real Madrid. Basically, PSG will be forced to sell him once they find a good substitute.
