Victor Osimhen was unable to help Napoli as they lost 2-0 to Granada in the first leg round of 32 of their Europa League game on Thursday night.
The Nigeria international was handed his 10th start of the season at Estadio Nuevo Los Carmenes but did not make much impact as his side lost against the Nasrids.
Osimhen has been struggling to justify the huge amount paid to Lille to secure his services, having only scored two goals and provided one assist since his arrival.
The centre-forward spearheaded Napoli attack against the Nasrids but despite his effort, Napoli were unable to continue in the winning way after defeating Juventus last time out to end a three-game winless run.
Napoli made several efforts but Granada were able to hold on to their lead and secure the win.
The 22-year-old featured for the duration of the game for Napoli in his 15th appearance this season across all competitions.
Osimhen will hope to make a meaningful impact in the second leg scheduled for February 25 at Stadio San Paolo.
