I think Osimhen will prefer to choose PSG than Chelsea, if he has consideration of a good team management for him to develop. Luis Enrique is undoubtedly much better coach than Maresca, and Chelsea currently is not a good place to have development for talented players. Chance to play in Champions League is a factor for a player to choose a club, but I don't think it's a big factor anymore, we have seen many top talents choose a better financial offer rather than chance to play in Champions League.
Players who prefer finances rather than playing in the Champions League are players who are no longer young in age at this time so they think that choosing the financial option will be much more appropriate than choosing the option of playing in the Champions League which is still not certain to win there. . But this is actually different from players who are still young and still aiming for a brilliant career in a famous team at this time, so that player will choose to be in a team that often enters the Champions League in order to prove that he deserves to be in that team.
