Authorities told to investigate possible match-fixing in Liverpool’s Champions League group

French authorities have opened an investiagation into possible match fixing in the UEFA Champions League tie between Paris Saint Germain and Red Star Belgrade, which ended 6-1 in favour of the Ligue 1 side.

A report in the French newspaper L'Equipe alleged that a senior figure at Red Star attempted to bet nearly €5million on the Serbian champions losing the game by five goals.

According to French publication L'Equipe, French prosecutors have begun looking into the match-fixing allegations after a tip-off by UEFA.

PSG said it was "extremely concerned" by the investigation.

Liverpool's next two Champions League games will come against Red Star, the first of which will take place at Anfield on October 24th.

"The club reaffirms its profound attachment to the fundamental principle of sport, which is and always will be the integrity of its competitions".

"The statements in this article seriously undermine our image and the club's reputation", the Serbian champions are quoted as saying.

A Red Star Belgrade spokesman, Nebojsa Todorovic, told AFP: "I can not comment on this in any way".

Red Star's deputy spokesman Nebojsa Todorovic informed Agence France Presse that he "cannot, in any way, comment on this", while the spokesman for Serbia's football association, Milan Vukovic, was unavailable.

The French newspaper claim UEFA alerted France to a possible bet made by one of the club's directors on his team losing the game by five or more goals.
