At the 25-year old, Osimhen will have like next 3 to 4 years to improve and reach to his best capability of performance. Besides the current contract expiration date, the potential of improvement and ageing effects on the player, will be two biggest factors for any big club that are considering to spend big money for Napoli and Osimhen.
I agree with you. In fact, the prime age of a football player is around 25-30 years and that is the age when a footballer will be at the peak of his performance. Osimhen is now 25 years old and I think it doesn't matter if another club wants to pay Napoli 100 million euros because Osimhen is still in his early prime. But at the moment I see Napoli set a price of 130 million euros for Osimhen and because of that many clubs are still not making an offer. I heard news that PSG is willing to buy Osimhen if the price is around 100 million euros and that is indeed a normal price considering Osimhen's age and current statistics.
Napoli have reduced his price but PSG has not shown any interest yet maybe the are still considering whether to buy him or not. Osimhen will be at his peak again if he can move to another club because he will want to put in his best performance and play with passion for the club just like last two seasons in Napoli.
Osimhen was the one that caused the problem for himself, if he knows that he will not play in Napoli for long why didn't he accept offers that was coming from various clubs when he was hot and in his peak performance after he won Seria A title last two seasons.
