More rumors today about Osimhen.
As we already know they already announced that he leave Napoli, he will probably go to PSG at this point over Mbappé.
I have searched Fabrizio Romano profile I didn't see any information about Osimhen leaving Napoli and going for either of the club you mentioned. The last time Fabrizio interviewed him was when he said 60% of rumors about him is because some of his fans want to see him play in the Premier, he said he appreciates them for that but he don't have any information about it his future with any club until further notice and because I think he has an active contract with Napoli until 2026, he might stay there.
I think PSG are not hungry to look for Mbape replacements, we have some many able guys in the European leagues that are good than Victor Osimhen and Mbape but because fame is around them right now, others are clouded by that but I'm sure that if they search properly, they will get another better player the way they got Mbape at younger age.
Fabrizio Romano is a journalist who happens to be getting the right information about the transfer of most players but that doesn't mean that he does report about every football transfer before they're sealed and that's why I don't think it's a good idea to always expect him to talk about every football transfer.
Victor Osimhen have been able to prove himself to the world of football that he's one of the best strikers in the world so keeping him at Napoli for a longer time I think will always be a problem for the club's management as he'll be definitely getting offers from European clubs of which some of them are even bigger than Napoli in terms financially and otherwise. Kylian Mbappe has confirmed that he'll be leaving Paris Saint Germaine at the end of the season and now the club is hunting for another big striker that'll replace him at the club when he finally leaves which I think Victor Osimhen will make a good replacement for Kylian Mbappe.
