I believe there is some uncertainty among the interested clubs whether Osimhen is a player who can have an excellent season in the Serie A with a club like Napoli that was performing extraordinarily last season, and then can have a season that is more average than excellent. This would still be ok if the price for Osimhen wouldn't be far more than 100 million. That is a risky investment when there is still doubt that he can constantly score this number of goals for years in a row.
It looks like Napoli is taking advantage of the transfer moment this time to sell Osimhen at a fantastic price, it is reported that Oshimhen's price has exceeded 150 million pounds. There are only a few Clubs who can afford that price, the figure is suitable for a player like Mbappe, but for Oshimhen it is far below Mbappe. lastly the offer from PSG has been rejected by Napoli. If Napoli were to charge that much it would likely be that Osimhen would stay at the Club, and I think that's what they want. By setting a fantastic price, the clubs who want his services will think twice about hunting for Oshimhen's signature.
With the step of increasing the selling price, Napoli can continue their togetherness to defend the title next season, that way they won't have to bother looking for new stickers. Hopefully they can defend the title with the presence of new coach Rudi Garcia. Even though it will be difficult, with a squad that is still the same as last season, I don't think it's too much trouble.
