Lille sporting director Luis Campos said Victor Osimhen was on his radar for four years before his signing in the summer.
Osimhen heralded his arrival to the football world at the 2015 Fifa U-17 World Cup in Chile where he won the Golden Boot with 10 goals and two assists, and also the Silver Ball as Nigeria emerged champions.
Although he was unable to establish himself at Wolfsburg, the centre-forward proved his readiness for the top-level challenge last season when he scored 20 goals across all competitions for Sporting Charleroi.
