This summer their president said it wants 400 mil for Osimhen.
I doubt he will leave for less than 150.
Really it's a fantastic figure that the club wants, but recently Osimhen has agreed to a new contract that will soon be completed at the beginning of 2024 in addition to Victor Osimhen will experience a fairly high salary increase, even the media said he had the highest salary in the history of the Napoli club.
This means Chelsea will not have the opportunity to buy Osimhen if he extends his contract until 2026, the clause value is €130M according to sky sport but it could be even higher.
