He is 1.88m (6'2") tall, weighs 85 kg (168lbs) and wears the number 39 shirt. His qualities are his speed and technique, but positioning, heading and tactical sense are his weak points.
He has played 138 matches in the first division and scored 33 goals. This season, he played 17 matches as a holder and 1 as a substitute, scored 6 goals, played 1407 minutes, and had 1 booking.
He was soon spotted by Rennes. The first time he played in the French first division was the 28th of July 2001 in the match Rennes-Auxerres (0-5). In his first season in the first division, Piquionne scored 3 goals in 20 matches. In his second season (2002-2003), he scored 10 goals under the coaching of Vahid Halilhodzic. New coach Laszlo Bölöni, arrived, and the rapport between them wasn't good, nor with his fellow-team-member Alexander Frei, ending the 2003-2004 season less then satisfactorily.
Saint-Etienne were interested in him, and he didn't have any hesitation accepting the chance to play for this new team.
Piquionne signed a 4 year deal for 4.5 Million Euros with Olympique Lyonnais on the 31st July 2008. He will wear the number 39 shirt.
He was surprisingly called up to the squad against Lithuania, 24 March, 2007, Euro 2008 Qualifying, but did not play. He made his international debut for the France national football team in a friendly against Austria on 28 March 2007.
He won another cap for France B against Slovakia in August 2007.
