Osimhen, 21, has been at the centre of a transfer soap opera with Manchester United and Liverpool reportedly showing late interest.
But his move to Napoli now seems close after he underwent a ‘rigorous’ medical on Saturday morning.
There are varying reports on how much Napoli will pay from Osimhen from €50m plus bonuses to €81m.
However, with his agent dramas now sorted, his transfer to Napoli could be made official at any time.
Lille owner Gerard Lopez gave a ‘no comment’ response when asked about the transfer on Saturday night.
