Both clubs moved swiftly to deny any wrongdoing in the 6-1 victory for the Ligue 1 champions and called on Uefa to open an immediate investigation.
Paris Saint-Germain and Red Star Belgrade have both issued statements denying any wrongdoing after a report in L’Equipe stated that the 6-1 Champions League victory for the home side is to be investigated for alleged match-fixing.
The French daily reported that Uefa had been alerted to a possible case of rigging after a “reliable” informant claimed that a Red Star director had placed bets totalling five million euros on the Serbian side losing by a margin of five goals in the Group C fixture.
“It was with the greatest stupefaction that Paris Saint-Germain discovered this Friday an article on the L'Equipe website regarding suspicions of match-fixing concerning the UEFA Champions League game with Red Star Belgrade on 3 October, suspicions regarding the alleged actions of bettors from Serbia,” PSG said in a communique.
“The Club categorically rejects any and all direct and indirect implication in relation to these suspicions and would like to point out at no moment has Paris Saint-Germain been approached by the National Financial Court in charge of the investigation.
“Paris Saint-Germain remains at the disposal of the investigators and will not tolerate the slightest attack on its reputation nor that of its officials. To that end, the Club reserves the right to take legal action against any party that makes defamatory statements against the club and/or its officials.
“The Club reaffirms its profound attachment to the fundamental principle of sport, which is and always will be the integrity of its competitions.”
Red Star demand Uefa investigation into match-fixing claims
Red Star also reacted to the allegations with a strongly worded statement calling on Uefa and the relevant authorities in France and Serbia to open an immediate investigation.
“Red Star with highest anger and abomination rejects the story L'Equipe published today about a suspicious result of the PSG-Red Star match and the involvement of anyone from our club in possible wrongdoing," the Serbian club's statement read.
"The article can harm and bring big damage to our club's reputation and that is why we insist that UEFA and investigators in Serbia and in France investigate the whole story and get the truth.
"Today's technologies and other mechanisms are so improved that it is basically impossible to leave this case unsolved.
"Red Star expects to get the truth at short notice, to take off any doubt about our involvement in possible wrongdoing."
