Osimhen has never forgotten the role Amuneke played in launching his career, lavishing praise on him during an acceptance speech when voted the best player in Africa.
"Special thanks goes to Emmanuel Amuneke. Without him I do not think I would be standing here holding one of the most prestigious awards in international football," he told the audience in Rabat.
Spotted by scouts in Chile, Osimhen moved to Europe, but his scoring skills deserted him when he joined Wolfsburg.
He failed to score in 14 matches and was loaned to Charleroi, where he rediscovered his scoring touch, netting 12 times in 25 matches.
Next stop for the Nigerian was Lille in neighbouring France. He spent one season there, averaging a goal every two matches.
Napoli splashed a club record 70 million euros in 2020 to sign Osimhen and he repaid the faith in him by helping the club end in 2023 a three-decade wait for a Serie A title.
Osimhen was hot property and the media linked him with a move to the Saudi Pro League, Chelsea or Paris Saint-Germain.
But he went to Istanbul-based Galatasaray instead, first on loan, then permanently. In Turkey, he has maintained his ability to score frequently.
Osimhen has been an equally prolific goal poacher for Nigeria, scoring 31 in 45 internationals since his 2017 debut, including four in a 2024 AFCON qualifier against Sao Tome e Principe.
In recent months, he bagged a hat-trick against Benin and two against Gabon in 2026 World Cup qualifiers.
But the Super Eagles will be notable absentees from the global showpiece next year after losing the African play-offs final against the Democratic Republic of Congo on penalties in Morocco.
Osimhen was forced to retire injured at half-time against the Congolese, and many Nigerian supporters blamed the loss on his absence.
He is no stranger to injuries and often wears a protective face mask after sustaining a broken cheekbone and eye socket playing for Napoli.
