Son of former Toulon centre, Martial Cottin, Yoan joined the Toulon junior ranks at the age of five and has been with the club ever since.
Cottin's father helped with the development of Marc Andreu, who in turn coached Yoan at u7s.
From a young age, Cottin showed maturity beyond his years and at the age of 20, he made his first start for Toulon in the Champions Cup clash against Newcastle during the 2018/19 season having made his TOP14 debut in October 2018.
Cottin went on to feature for Toulon's senior club as he went into the 2019/20 season.
