Well, PSG plays in weak legaue, they are overpaying players to attract them there, neymar "barca's future" went there, now he realised his market worth is going down and he isnt attractive to sponsors as he was at barca, thats the reason he wants out, veratti wanted out, they just gave him better salary, he is happy there now, about de ligt, i dont believe he earn much less at juve then he would at PSG, rabiot isnt that good so they didnt want to give him better salary, thats why he left, mbappe will also left psg, because he will want to play on higher level, ligue 1 isnt that. So what is exactly the problem with some players wanting out after some time at PSG, when thats completely normal thing
Its all about money, PSG doesnt put gun on players head and forcing him to stay there, they have absolutely right to demand what ever they want from barca to let neymar,
