The attacker came as a second-half substitute but could not help his side from falling to their visitors
Nigeria striker Victor Osimhen is hopeful Napoli will bounce back from their 3-2 Europa League defeat to Spartak Moscow at the Diego Armando Stadium on Thursday.
The 22-year-old started from the bench but was introduced in the second half, taking the place of Andrea Petagna, and ended up scoring for his team in stoppage time after converting Giovanni Di Lorenzo's pass.
"We stand firm as a team no matter the outcome. 100% we will be back," Osimhen posted on his official social media account.
