Osimhgen has not yet declared his final decision regarding his future. So far no comment has been coming from him regarding what's going to happen with his career in napoli. Osimhen probably leave from there in winter as long as there will be a good club will try to send a lucrative offer to get him. Chelsea needs to prepare a lot of money for him but the main problem was on the management of club since napoli was not willing to let him go as he has still a part from napoli's project.
In principle, the inflating by Viktor Osimhen and his agent of the situation with a grudge against the club is already starting to look a little fake and quite looks like preparing for the transfer of a player from Napoli to another club already in the next transfer window. Now the whole question will be how much the club would like to get for a football player, because I still think that the management of Napoli probably expected to solve the issue of selling a football player next summer, when a player with his game would help the club achieve good results and thereby raise his transfer value.
