With Napoli almost certain to have a new coach and Antonio Conte with his experience and achievements very likely being able to bring Napoli back to a better level, it is very likely that Victor Osimhen will stay at the club.
Previously, Chelsea was reported to be interested in this player, but at Chelsea there have also been changes in the coaching staff, so many changes will occur, including them no longer being interested in Osimhen.
My prediction is that Osimhen will remain at Napoli and Conte will need him as Napoli's goal machine next season, and he is still a valuable asset for Napoli.
Napoli should keep him, otherwise they will have difficulty finding a reliable enough goalscorer, especially as Napoli is not a club that is willing to spend large amounts of money in the transfer market then keeping him is the best choice.
Regardless of the loopholes Osimhen faced for a few weeks with Napoli, he still found so much belief in them and he'sore or less the fans' favorite too. So the news of his contract extension was definitely soothing to the team and fans too. Now it's certain that they'd keep seeing and benefiting from his unique style of football. He's being a key man at the Italian side and it was although very much unlikely for them to let him slip off their arm. He's just got more impacts to make.
Napoli themselves have seen the quality of player he is and they really don't want to let him go. It's his decision no doubt, but maybe he's just got to get experiences in a different club environment. Even though, he still has an achievement to deliver onto the team too. Since Osimhen joined Napoli, he's been their key player and he's been doing his striking job perfectly without errors, even in times of emotional derailment from fans and the coach, he's still being able to keep his mind focused.
He is in no wise the best thing that's happened to Napoli. He's the best addition to the team. Although Chelsea are having eyes on him but it's likely that Napoli won't let him slip without a very good replacement for him. His exit will place a threat to the teams performance subsequently and they may likely go back drastically.
