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.
In the past I had heard that Napoli management had opened a price for Osimhen worth €100 million and this meant that Napoli management actually had plans to sell the player but at that time Napoli condition was still fine, whereas now Napoli is experiencing a very deep downturn and need a player like Osimhen which would be a big loss for Napoli if they lost this player so management must try to retain him in various ways such as offering a bigger salary if he stays.
and on the one hand, in fact, if Napoli stays at Napoli, he will suffer a big loss in his career because Napoli has a bad reputation at the moment and it would be better if Osimhen tried to challenge a team from another, more appropriate league.
maybe it is certain that the rumors about Mbappe will leave, but the rumors about Osimhen who will replace Mbappe don't seem to be coming true because I believe that if Osimhen decides to leave Napoli, he will definitely choose to join a team from the EPL which provides more guarantees for the future which is brighter than being at PSG which in the end will end the same as when he was with Napoli.
