Fan favourite Jean-Michel Sigere joined the club at the start of last season and made his debut in the opening day 4-0 victory against Ware on 20th August 2011.
Jean-Michel went on to play 24 times for Grays Athletic in league and cup games.
He wanted to "thank the staff and supporters for making his time at Grays Athletic and enjoyable one and wish the club success for the coming season."
Jean-Michel leaves Grays Athletic to join up with Chatham Town, so fans will get to see him two more times next season, albeit in opposition colours.
Grays Athletic would like to thank Jean-Michel for his efforts as a Blue, and we would like wish him all the best for the future.
