Having impressed during his loan spell, Lyon has now decided to sign the winger on a permanent deal from Belgian side RWD Molenbeek.
A statement from the French club on Sunday said Nuamah has signed a four-year contract. The statement read: “CONFIRMED: Ernest Nuamah has joined us on a permanent deal until.”
Abedi Pele joined Lyon ahead of the 1993/94 campaign following his trophy-laden spell with rivals Olympique Marseille.
Essien was also on the books of the French side during his formative years and won two league titles with the club before moving to Chelsea in 2005.
Mensah also spent four years at Lyon, having joined for a €8.4 million fee from Stade Rennes in 2008.
Meanwhile, Nuamah will be hoping to establish himself at Lyon after his impressive debut season in the French topflight.
The young winger is already a full international and featured in Ghana’s victories against Mali and the Central African Republic (CAR) during last month’s 2026 FIFA World Cup qualifiers.
