Victor Osimhen and Napoil are close to reaching an agreement on a new contract.
According to Sky Sport Italia, both parties are working on the final details of the contract.
Osimhen will sign a new two-year contract which see him contracted to the Partenopei until 2027.
A release clause close to around €150m will also be inserted in the new contract.
Napoli president Aurelio de Laurentiis reportedly wanted to insert €200m release clause in the contract but seems to have bowed to pressure from Osimhen’s camp to lower it.
The Nigeria international was a subject of interest from Manchester United, Chelsea, Paris Saint-Germain and Bayern Munich this summer.
The 24-year-old was the top scorer in Serie A last season with 26 goals from 32 games.
