PARIS (AFP) The future of top French football side Paris Saint Germain is at stake if the club fails to rein in violent hooligans, French Secretary of State for Sport Rama Yade said Thursday. PSGs history of fan violence took a fatal twist with the death Thursday morning 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 their arch rivals Marseille on February 28. Amid widespread calls for violence to be eradicated around PSGs notoriously troubled Parc des Princes stadium, Yade said the club is now under even more intense pressure to act. The very worst thing possible has happened. Passion has been transformed into sordid, senseless and murderous rage. The love of the shirt has been replaced by hatred, for each other, for sport, and for life, said Yade. Supporters who kill each other should be punished with the utmost severity. The very survival of the club is at stake, said Yade. Despite their relative lack of success on the field, PSG are still one of the best supported clubs in the country although that reputation is tarnished by the delicate co-existence of several rival fans groups at the Parc des Princes. The deceased was reportedly a member of the 'Casual Firm group of supporters who congregate at the Boulogne end of the Parc, and was attacked by members of a rival group from the Auteuil end. After Thursdays death, PSG announced they had provisionally suspended all agreements that had been signed with the various supporters associations. Offering condolences to the fans family, the club added: We intend to fully investigate the consequences of this incident and then take the necessary action to help eradicate violence from in an and around the Parc des Princes and during the teams away trips. Once again the behaviour of a band of pseudo-supporters has plunged the club, its management, its shareholder, its sponsors, its players and its real fans into a state of sadness and dismay. We want whoever is responsible for this criminal act to be caught, interrogated and charged.
