‘You don't choose your past, but you create your future,’ philosophises the young midfielder, who has played for Sevran, Villepinte and Epinay. Mamadou arrived at the Stade Louis-II at the end of July 2019. After a very good first half of the season with the Elite Group (23 games for 5 goals), the player joined the professional squad for the second half of the 2023-2024 financial year, before making his debut against Toulouse in February 2024. The player played a further 5 games, including a start against Nantes in the final match (4-0). Injury prevented him from continuing this good form at the start of the 2024-2025 season, marked by the Club's Centenary. The midfielder from La Diagonale finally returned to the pitch in February 2025, coming on as a substitute in Monaco's historic 7-1 win over Canaris.
