I think bringing Mbappe isn't in Real Madrid's capacity but in Mbappe hands and PSG. If Mbappe has made up his mind to come to Madrid and PSG also accepts this,Real Madrid will pay for the transfer Instantly because they have tried their best after the world cup to bring Mbappe to Real Madrid but things didn't work out for them. Let's hope they will succeed to bring him to Real Madrid before next season so that he can add value to the club matches. If I am not mistaken,Real Madrid is the richest club and has all it takes to bring in Mbappe. If PSG feels remorse to let Mbappe go then they will be at lost by the time Mbappe contract is over with them.
the situation is confusing. because Mbappe reportedly refused to use the contract extension option for 1 year and his contract with PSG will expire next year. which means if he is not sold in the transfer market this season, Mbappe may leave PSG for free. I don't think PSG wants this to happen. because it would be a loss for PSG.
I think Mbappe has to make a decision, if he wants to stay then he has to be willing to sign a contract extension. but if you want to leave, then he must be willing to be sold in the transfer market this season. if he has problems with Madrid, of course, he will get offers from other clubs.
Hahaha, precisely because Mbappe did not extend his contract at PSG it is clear, that Mbappe showed that Mbappe already wanted to leave PSG and therefore Mbappe made the decision not to renew his contract. Thus, of course, PSG must be ready to lose Mbappe whatever happens because after all, the decision is not entirely on PSG because the main decision is the desire of the player himself. So that means, the club cannot hinder the player's wishes, if the player wants to leave then the player can leave but of course with some rules and Real Madrid are ahead to be able to get Mbappe.
