Serin is an electrifying attacking scrum-half, with a reliable kicking boot, that signed for Bordeaux since 2012, playing in over 120 games and scoring more than 400 points for the French side.
A member of the Parentis Sports Club before joining Bordeaux in 2009. His first-team debut came as a sub at home to London Irish in the Challenge Cup in 2012, before making his Top14 debut at the close of that calendar year.

Serin debuted for the French senior national side against Argentina in November 2016 and made further headlines when he came off the bench for his first game against World champions, the All Blacks and created a try with a fantastic behind the back pass for Louis Picamoles for Frances only try of the game.
In June 2016, Serin was named into the France team to compete for the autumn tour in Argentina, he played two tests on the tour at scrum-half. He came off the bench in all three autumn internationals. Serin featured regularly for France in 2017 but was omitted for France's initial 2018 6 Nations squad. He was then called into the squad to cover for the injured Morgan Parra.
2019 saw him sign a three-year deal with Toulon as he also went on to represent France at the Rugby World Cup in Japan. He went into the 2020 Top 14 season having made 13 appearances for the French giants. Serin continued to be a regular in the France squad and in November he led his country for the first time as he captained France against Italy in his 39th test match.
Injuries limited Serin's involvement for Toulon and France before he signed a new deal with Toulon in December 2021. His four-year extension, with an option of an added season, will see him remain at the club until at least 2025.
Serin heads into 2022 with 42 test caps under his belt.
