Mbappe has never been blamed because what should we blame the players who support the club? The defeat of only blaming Mbappe alone will actually be as naive as what was done to Messi and Neymar last season.
PSG's fault is the whole including Mbappe why is he not blamed himself? because it is impossible especially if you see how he plays on the field even though there are several occasions he still looks quite selfish but blaming someone whose performance is good obviously it would be ridiculous.
I still haven't seen any official information saying Mbappé will renew his contract with PSG. If he continues to renew his contract, it means that in his youth, he will be associated with the PSG club. Staying here really didn't bring him any prestigious titles. Power and money were boring to him. Real Madrid is waiting for him, and this is a club that will help him with many things. Mbappé turned 25 but never won a Champions League title or the Golden Ball. If he wants to become a legend, he should go to Real Madrid.
Although it is still unclear but indeed this is something that could make sense because PSG does not want to lose money considering he will leave for free and the 1 season contract renewal is only intended as a formality that PSG will not lose money on this player by still being able to be valuable to offer.
There are several sources that say this but maybe I'll just take one here.
