Mbappe does not want to extend his contract but interested clubs like Real Madrid can still be patient until next summer transfer. Thus, Real Madrid and Mbappe seem to have started the game so that Real Madrid can bring Mbappe in for free in the summer transfer. Therefore, this situation and conditions make it possible for PSG to lose the game because after all, PSG also failed to extend Mbappe's contract. But yes, maybe this incident will also be a big lesson for PSG, that money cannot always take sides because in fact Mbappe also still chose to leave.
I am also suspecting that Real Madrid and Kylian Mbappe have reached an informal agreement that will make him move freely to Santiago Bernabéu. He wanted to play a smart game but PSG became smarter. There have been offers from other clubs including Arsenal, Liverpool, and Al Hilal. Arsenal are willing to swap Gabriel Martinelli to facilitate the deal but the League 1 striker has rejected the offer to come to the EPL. I don't think Liverpool have the financial power to buy Mbappe. Al Hilal is offering the striker € 2 million per day, which is out of the world wage. But it seems the striker knows what he wants and he has decided to move to Real to win European trophies.
Real Madrid seem relaxed about Mbappe's situation even though the player has wanted to play for Real Madrid a few seasons ago. I'm not sure Madrid are serious about signing him, but they will still open the door for Mbappe with a free transfer. Things will be updated soon, but PSG will obviously have to pay a loyalty bonus if Mbappe doesn't sold.
Real Madrid is relaxing because Mbappe has shown interest in moving to the club. But PSG is not willing to let him go just like that. The French team will sell him to the highest bidder and make a profit from the transaction. If Mbappe is not sold this in this transfer window, PSG will bear the consequences because he will leave freely next season. I expect Real Madrid to come up with a good offer that can make PSG let him go.
