Nothing strange if we do get to sign some cream of the crop and cherry on top, in fact we have already done it prior to the new owners so whatever Todd is doing it's not new. The only new thing is that he picked Potter for a long term project, Roman ultimately didn't care who's at the wheel as long as the ship gets the prize.
With that said, I firmly believe that Mbappe can't decide to leave PSG. Verratti was supposed to go to Barcelona and he simply wasn't let to change clubs during his best years, now he's 30 years old and PSG will let him leave once it's clear to everyone there that his time has passed, he has spent 10 years there. PSG owners don't care to gain from selling players, Mbappe might even dream of playing for Real Madrid but that will have to wait till he has actually passed his peak or something like that, after all look at his current wages.
