Napoli have been chasing the Nigerian striker, scorer of 18 goals this season, for several months.
And according to Gianluca Di Marzio, an official meeting is planned in the next day or so to try and make progress.
The Naples club are in ‘continuous contact’ with Lille to try and land the striker ahead of the competition.
Osimhen, 21, is on the radar of a number of clubs following an outstanding year for Lille in Ligue 1 and the Champions League.
But Osimhen has been and remains their priority and the next days could be decisive in their pursuit of him.
