It seems to me that this is nothing more than a rumor, and at once for a combination of many reasons. Firstly, PSG spent so much money on Mbappe that no club can buy him. Secondly, everyone already understands that buying Mbappe means a huge number of problems with him - he is very harmful and capricious. I don't think that Perez is suicidal and will take Mbappe to Real as such a transfer would destroy the whole team spirit of Real. Thirdly, does Mbappe really think that he will do better at Real Madrid than at PSG? Maybe, but now, in order to prove something, he needs to move to the Premier League.
