French authorities are investigating claims that a Red Star Belgrade official tried to fix the Serbian giants' 6-1 Champions League Group C loss away at Paris Saint-Germain earlier this month.
The allegations relate to suggestions that a senior figure from Red Star Belgrade tried to place a bet of nearly €5 million on his team to lose the game by at least five goals, and they did just that, falling to a 6-1 defeat.
Red Star Belgrade now sit bottom of Group C of their Champions League group.
"The statements in this article seriously undermine our image and the club's reputation", the club said.
Red Star have dismissed the allegation absolutely.
A PSG statement said: "It is with the utmost amazement and indignation that we learn the information you are sharing with us today".
In response to the L'Equipe story, Red Star released a statement denying the accusations.
UEFA said it did not comment on ongoing investigations.
"At no time was any club member asked to discuss matters other than those strictly related to the organisation of the match, namely meetings, visits and other official lunches around every UEFA Champions League match".
Shortly thereafter, Neymar, completing his hat-trick for the night, scored a free-kick to restore the 5-goal difference and give PSG their 6-1 win.
"On this occasion, PSG reiterates our attachment to fundamental sporting principles, the integrity of competitions & consequently refuses any form of practice that could call that integrity into question".
When approached for comment regarding the match-fixing allegations, Uefa told The Independent: "Uefa never comments on potential, or the existence of, investigations into alleged match-fixing as to not compromise the process of such investigations".
