Berson played for Nantes, Aston Villa, Auxerre, Levante, Toulouse, and Vannes before retiring in 2013.

He was a member of the successful Nantes side that won the Coupe de France in 1999 and 2000, followed by the Division 1 title in 2001, and the Trophée des Champions in 2002.

Berson began his career with Nantes and made his senior debut during the 1999–2000 season, going on to start in the victorious 2000 Coupe de France Final.

In January 2005, Villa signed Eric Djemba-Djemba in an attempt to replicate the successful partnership they had formed at Nantes, where they played 50 games together.

Released by Toulouse in the summer of 2010 due to budget cuts, Berson remained without a club until signing a two-year contract with Vannes in June 2011.
