Napoli struggled to make an impact in the first 45 minutes, failing to register a shot.
Calzona served as the club’s assistant manager between 2015-2018 and the technical coach between 2021 and 2022.
On Monday night, the Nigerian contingents travelled to Bouake for the crucial match against South Africa, but Osimhen could not make the trip.
Osimhen will stay put in Abidjan, where the team has been based since the tournament began more than three weeks ago.
Barely 30 seconds into the game, Nigeria nearly found the back of the net, but Alex Iwobi’s shot was saved by the goalkeeper, Jesus Owono.
“It is not the most beautiful victory.’’
The last 16 is played over four weeks at the start of 2024.
Osimhen earned a spot in the Serie A Team of the Year alongside notable players.
“In any case, if Victor perceived any offence towards him, this was not what the club intended,” Napoli said.
