The Super Eagles star leaves the French Ligue 1 club, Lille this summer to link up with Italian Serie A side, Napoli.
Osimhen joined Les Dogues last year from Royal Charleroi, but he leaves after just a season which saw him score 18 goals and provide six assists in 38 games.
Although there were several top European clubs interested in his services, Napoli won the race for his signature, and Osimhen will be donning the shirts of Gli Azzurri next season.
The 21-year-old joins the Gli Azzurri on a five-year-deal worth 80m euros according to Napoli owner, Aurelio De Laurentis.
However, Osimhen will be moving to a league where Nigerian strikers have struggled in the past.
The Italian Serie A has not been a happy hunting ground for Super Eagles strikers, and Soccernet.ng takes a look at how some of Nigeria’s hotshots have fared in the league ahead of Osimhen’s potential move.
The retired Nigerian footballer turned football agent played for six different clubs in the Italian top-flight with over 100 appearances.
Makinwa started his Serie A career with Reggiana before further stints with Chievo, Modena, Atalanta, Palermo and Lazio.
But despite 120 appearances across these clubs, the Lagos-born centre-forward scored a paltry 16 goals. His Serie A journey ended in 2010 when he joined Greek club AEL Larrisa.
