I'm not sure if this news has been confirmed but what I know is that PSG also defended Mbappe to stay at PSG. because it will be very bad if Mbappe leaves PSG like there will be no strength anymore after several top players leave PSG.
I can't imagine PSG will be able to do well in the summer if Mbappe does leave PSG but I hope not. because PSG really needs the best players like Mbappe.
I doubt the news, Maybe he likes to leave, but as usual, he will not. Mbappe has been one of the major players in that PSG team. In important games where he does not play, we always see how PSG struggle because that his ability to make quick runs and score with just a touch will be missing in the game. With Messi now out of PSG and Neymar set to leave too, Mbappe knows there will be more responsibility for him. PSG will get new players in the transfer market, that can majorly play with him to win the champions league in PSG, he is not leaving.
I don't think Mbappe has any intention of leaving anytime soon despite all the rumours about him not happy with the club. Mbappe still has more than a year contract with PSG and being one of the most important and respected player I don't think he will just leave the team to another club unless PSG don't want him again which I think the club can do without him right now. The absence of Messi and hopefully Naymer will be felt in the team and if PSG does not replace the players and Mbappe leaves the team, it's going to be bad for them and I doubt if the management of the club will allow that to happen.
The target of PSG will be to get a solid team again next season to fight for the Champions league and Mbappe is already a pillar in the team so letting him to go will be like PSG trying to start all over again to build a new team which means they may not be a major contenders in the French ligue 1 and champions league.
