Victor Osimhen is still in Nigeria but is expected back in Italy next week to start the intensive phase of his recovery work.
The 24-year-old is currently sidelined with a hamstring muscle injury.
Osimhen sustained the injury in Nigeria’s 2-2 draw against Saudi Arabia on October 13.
The forward has missed the club’s last three consecutive games due to injury.
Osimhen has remained in Nigeria since suffering the injury, leaving Napoli waiting for his return.
Napoli hope he’ll be fit to face Atalanta on November 25, a match that could prove vital in the race for the top spots in Serie A.
He has scored six goals in eight league appearances for the Partenopei this season.
