As European police investigators say hundreds of football matches have been fixed across the continent, ITV News looks back at some of the sport's biggest match-fixing scandals.
The French club's president Bernard Tapie was found to have bribed Valenciennes FC players into throwing a league game, enabling Marseille to win the French League and giving them more time to concentrate on the Champions League final against AC Milan. The club were later stripped of their Ligue 1 title and relegated, while Tapie was sent to prison.
Referee Robert Hoyzer confessed to trying to fix matches for Croatian crime syndicates. The €2m match-fixing scandal included attempts to fix matches in the second division, third division and German Cup. Hoyzer was sent to prison for two years.
The “Calciopoli” scandal engulfed Italian football with some of the country's biggest clubs implicated. Teams including AC Milan, Lazio, Fiorentina and Juventus were found guilty of rigging games by selecting favourable referees. Juventus were relegated to Serie B and stripped of their two Serie A titles from 2005 and 2006, while the three other clubs were deducted points.
Suspicions were raised when two matches at a friendly tourament in Turkey - Latvia v Bolivia and Estonia v Bulgaria - produced a total of seven goals, all of which were penalties. Six match officials were found guilty of "passive corruption" and "unlawfully influencing match results" by Fifa's disciplinary committee. Fifa handed lifetime bans to the officials, who were from Hungary and Bosnia.
