The central defender was born in Saint-Pol-sur-Mer and began his career at USL Dunkerque, where he played for four seasons before earning a move to RC Lens. In his first season at Lens he helped them to the French title and played a key role in the clubs run to the UEFA Cup semi-final in 2000.
On 6 July 2005 he signed for Scottish Premier League club Rangers on a free transfer. After making a positive start to the 2005-06 campaign, scoring in Rangers' 3-0 defeat of Livingston on his debut, Fanfan fell out of favour with Alex McLeish and hardly played a game after September. Incoming Ibrox manager Paul Le Guen deemed him surplus to requirements in July 2006 and he was released on August 31, hours before the closure of the transfer window.
After being more than a year without a club, he joined Al-Sailiya from Qatar for a spell. In June 2009 Fanfan announced his retirement from football.
