Edouard Mendy

Mendy joined the youth academy of Le Havre AC at the age of 13. After being stuck behind Zacharie Boucher in the talent pool, Mendy dropped down levels to play with CS Municipaux Le Havre. He started his professional career at AS Cherbourg, who were then in the Championnat National, the third tier of the French football league system. He stayed in Cherbourg until the summer of 2014. It was then that Olympique Marseille took a gamble on Mendy and signed him to their team. He played the 2015–16 season on Marseille's reserve team, but was again stuck behind another talent, in this case it was Florian Escales that played ahead of him on the Marseille B team.

In search of regular playing time, Mendy joined Reims during the 2016–17 Ligue 2 season. Starting in place of Johann Carrasso who was sent off for a red card, Mendy kept three clean sheets over his next seven games. The next season, Mendy cemented his role as the starting goalkeeper on a team for the first time, as he helped Reims win the 2017–18 Ligue 2 title as they were promoted to Ligue 1 for the following season.

On 6 August 2019, Rennes announced they had signed Mendy from Reims for an undisclosed fee.

On 24 September 2020, Chelsea announced they had signed Mendy on a five-year contract for a fee reported to be £22 million. Chelsea head coach Frank Lampard revealed that former Chelsea goalkeeper and current Technical Advisor, Petr Čech (who coincidentally also joined Chelsea from Rennes), played a prominent role in the decision to sign Mendy. On 29 September, Mendy made his debut for Chelsea against Tottenham Hotspur in the EFL cup round of 16. Chelsea lost the match 5–4 on penalties after a 1–1 draw.
