Napoli seems to be getting karma because they were too insistent on keeping Osimhen when the offer came from PSG, now they are in an unfavorable situation because Osimhen status is still unclear, whether he will be sold to Chelsea immediately and include Lukaku in the deal or he will be kept for another season. The defeat in the first game shows that Napoli's quality is not at its best, they must immediately get out of this situation to get their first points this season. Napoli must complete the transfer soon if they want to sell Osimhen, if they continue to hold on to the Nigerian, his price may drop if he fails to maintain his form.
In addition to Osimhen's price which could drop because he continues to insist on being kept, Napoli could also experience more defeats because there is one player who may no longer be happy to be in the Napoli squad, namely Osimhen. So Napoli must immediately make a wiser decision if they want their own team's condition to improve because losing badly without reply in the first match this season is certainly very painful for Napoli, especially if their opponent is not strong enough but Napoli is unable to score a single goal against Verona.
Napoli needs Osimhen. That's why they don't want to sell him. If they are going to sell him, it should be a very high amount of money. They have to convince the team, they have to convince the player to leave. Osimhen may want to leave the team right now, but the conditions are not yet fully mature. If Paris Saint-Germain or Chelsea want him, they have to pay a very high transfer fee. If this payment is not made, Napoli may not be willing to sell the player.
