Osimhen had a successful loan spell with Galatasaray last season, scoring 37 goals and providing seven assists in 41 games. Despite this, the clubs are struggling to reach a mutually acceptable agreement on the transfer terms.
Napoli wants to sell Osimhen for his full release price of €75 million. However, Galatasaray's offer matches the asking price but proposes to pay it in installments instead of in one lump sum.
Napoli's president, Aurelio De Laurentiis, has now made new demands, including specific payment schedules and a request for a stake in Osimhen's future earnings. He also wants a guarantee that Osimhen will not be sold to an Italian club for three years.
