PSG defender Sammy Traore (R) vies with Nice's forward Mamadou Bagayoko (L) during their French L1 football match Nice vs Paris-Saint-Germain on March 20, 2010 at the Ray Stadium in Nice. The match is played behind closed doors after supporters invaded the pitch during the Nice vs Monaco match on January 30, 2010 following a decision by the French Football League. The PSG will also play its next two matches behind closed doors after the club failed to rein in violent hooligans. PSG's history of fan violence took a fatal twist with the death early March 18 of a 37-year-old man, named only as Yann L., who suffered a beating by fellow PSG supporters on the fringes of a match against arch rivals Marseille on February 28.
