The Super Eagles striker scored a beautiful brace against Nantes in the French Ligue 1 to lead Lille to a fine opening day win.
The 20-year-old only joined Lille a few weeks ago from Sporting Chaleroi of Belgium for a reported $25 million and has already started paying back a chunk of that huge transfer fee.
It took the 2019 AFCON bronze medalist just 19 minutes to grab his goal that gave Lille the lead against Nantes, Sunday afternoon.
The goal took Osimhen into the record books making him the first Nigerian player since Austin Okocha (PSG) in 1998 to score on his Ligue 1 debut.
Nantes got a lucky break early in the second half as a Zeki Celik own goal drew level for the away side.
But Osimhen would just not be denied his debut win. With ten minutes of play left of the game, the U-17 FIFA World Cup winner rose to the occasion to slam home the winner off a Zeki Celik assist.
