Rouen born Duhamel is a referee since 1984. He received his Fifa badge in 1999 and is an UEFA Elite Category referee since 2006 but what many of our reporters saw coming: he was demoted to the 1st category in 2012.
He was active in the Meridian Cup (Italy 2001).
He made his debut in the Champions League September 2007, the match Chelsea-Rosenborg (1-1).
His list of matches is impressive.
In 2011 he seemed to have been demoted, at least in tournaments, going back to doing Europa League matches while refs from lower Categories entered the Champions League. Like his fellow country man Antony Gautier.
