Almost 1000 top-flight football matches are suspected to have been rigged in the past five years, according to alarming figures from the world's leading match-fixing watch-dog.
Sportradar, which monitors around 40,000 games a year - including every Premier League, FA Cup and Champions League fixture - deemed 997 elite domestic global matches "highly suspicious" between May 2009 and November 2014.
An analysis of its data by Holland's Asser Institute, as part of the first study into the dangers posed by different types of betting to the integrity of sport, found that fixers were three times more likely to target top-flight matches than second-tier competitions.
Although Sportradar does not usually monitor divisions below those levels, the revelation casts doubt on the received wisdom that elite matches are under less threat than lower-league games.
Of a total of 1625 suspicious fixtures since 2009, around a third prompted bookmakers either to partially or completely remove the betting offer on the match in question.
