A high salary is apparently not as valuable to him as playing for the club he has dreamed of since childhood. The fact that they are treating him like this now I think will only make it worse for the team, because in the Champions League without him it will be very difficult for them, unlike in the French league. If they make it out of the group stage, they are unlikely to go far without him
Do you know what the reason is for Mbappe to more or less boycott everything? It is not PSG, it is Mbappe who wants the massive bonus for the new season while he wants to leave the club at the same time. But you have to understand that this is a bonus he would get when he stays. His plan is to get PSG to pay him his bonus and also to let him go because otherwise they would lose the total transfer fee if he stays another year. That is his calculation. If Real goes up with the price, PSG could take a chunk of that money and also pay him a bonus he never deserved. Maybe it is not as idealistic as you think as if he just wants to go to the club he has been dreaming of since his childhood but now his bosses destroy his dream.
Yes, Mbappe is obviously a cynic, and all the fairy tales in 2023 about "my favorite club since childhood, etc." it's not even funny anymore. But he is in his right, he fulfills the contract and there can be no claims against him. PSG is another matter - they paid him for something, but they are trying to pressure him to get more from him than he was obliged to do. This is both unethical and somewhat illegal.
Yes absolutely, he isn't behaving against the contract.
But why do you think that PSG is pressuring Mbappe? I mean we have no idea what the truth is because we can only read what's publicly written and maybe listen to some statements, but even then we won't know the truth in full. But as far I understand this, Mbappe wants money for a season from PSG that he actually doesn't want to play for PSG. There are contracts and there is conduct. What Mbappe is doing is contractually compliant, but really bad conduct. He is loaded with greed that I am still surprised he didn't blow like a dynamite from the inside. Never enough for the guy and this does not only refer to money, but to his goals in general. He definitely wants to play for Real Madrid, but he wants every penny he can get even if he needs to become a business MF. When you watch some videos and have a closer look at his attitude, he changed so quickly with success flying his way. What a genius player and a questionable character.
