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. The following campaign, Nantes were crowned champions of France for the eight time, with Berson making 29 league appearances. He also played as Nantes won the
2001 Trophée des Champions. Having featured for the club consistently over a four-year period, he was transferred to
Premier League club
Aston Villa in the summer of 2004. 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. However, six months later, Berson was back in France, having joined
Auxerre on a season-long loan. In the summer of 2006, he was transferred to
La Liga side
Levante. He played regularly for the next two seasons before returning to France with
Toulouse in 2008. 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. ==References==
