Ingla told reports that Osimhen’s transfer to Napoli has reached the final stage of completion.
"We are in the last stage [of discussions]. The player has made his choice. It is a regret to see him leave but we must be aware of the strength of the market,” Ingla said.
"We do not hide our economic model. We must not only consider the amount of the transfer but also the salary that is offered to the player.
“We are not a final destination. With us, players thrive. We use their talent but we also build their careers. We are also in this process. It is the life of a club and the market. For him and his family, this can be an exceptional opportunity."
