The striker scored his debut goal with a finish against Atalanta in the 43rd minute.
After scoring, Osimhen held up a shirt with the inscription “End Police Brutality in Nigeria”.
He has previously shown his support for the #EndSARS protesters in Nigeria.
On October 12, the striker took to Twitter saying the power of the people outweighs those in government.
“The power of the people is always stronger than the people in power. remember DAT #ReformNigeriaPolice,” he tweeted.
Two days earlier, he also called for an end to police brutality in the country, insisting that the human rights abuses by the Special Anti-Robbery Squad (SARS) must end.
This comes three months after Napoli signed him with a $94.6 million to bring Nigeria forward to southern Italy on a five-year deal.
Osimhen’s move to the Gli Azzurri trumps the prize Arsenal paid for Ivory Coast forward, Nicolas Pepe last year.
