AJ Auxerre have secured the future of Lassine Sinayoko, confirming that the forward has signed a contract extension which will keep him at the club until 2027, reinforcing a partnership built steadily over nearly a decade.
The new deal rewards a player whose progression has mirrored Auxerre’s own journey in recent seasons.
Sinayoko arrived in Burgundy in 2017 from Entente Sannois Saint-Gratien and has risen through the club’s ranks with patience and persistence, gradually establishing himself as a key figure in the first team.
His early years were spent in Auxerre’s youth system, where he featured prominently for the under-19 side before earning regular minutes with the reserve team.
That period proved decisive in preparing him for senior football, and his long-awaited first-team debut came in April 2021 away at Niort.
It marked the beginning of a steady ascent, soon followed by his first senior goal for the club in the Coupe de France during a tie in Chambéry.
The 2021-2022 campaign represented a defining chapter in Sinayoko’s development.
Auxerre’s successful push for promotion back to Ligue 1 was accompanied by his growing influence within the squad, as he contributed to a collective effort that restored the club to the top flight.
The following season brought his first experience of Ligue 1 football, highlighted by a memorable goal against Paris Saint-Germain, underlining his ability to perform on the biggest stage.
After Auxerre’s return to Ligue 2 BKT, Sinayoko’s importance only increased.
He delivered eight goals during the campaign that ended with another promotion, this time crowned by a league title, further strengthening his status within the squad and among supporters.
That upward trajectory has continued.
During the 2024-2025 Ligue 1 season, Sinayoko maintained a consistent attacking output, scoring five goals and providing nine assists.
His influence has carried into the current campaign, where he has already found the net six times, confirming his role as a reliable offensive presence.
For Auxerre, extending Sinayoko’s contract is a statement of continuity and trust.
It reflects a journey defined by gradual growth, resilience and measurable progress, while offering stability as the club looks to build on recent achievements
. For the player, the agreement represents recognition of a path forged step by step, and an opportunity to continue writing his story in Burgundy colours.
