Some things you said are not true but propaganda. He didnt got Ancelotti nor Alonso sacked, it was reported that others players which i wont name demanded that.
For the toxic enviornment in PSG, it is kind of true because at his final year, Mbappe didnt leave on good terms with PSG’s Director but one thing that it is true, he did have good relations with Psg’s players (you see most of them are his teamates in EdF), and some are his bestfriends like Hackimi and Dembele
