European police have announced that 380 matches, including a Champions League tie, across Europe have been fixed.
An investigation has revealed that 425 match officials, players, club officials and criminals are alleged to have been involved in match-fixing incidents.
Matches that are thought to have been at the centre of corruption are understood to include European Championship qualifiers, World Cup clashes and two Champions League ties, one of which was in England.
While the authorities have not confirmed which European tie on English soil was fixed, Europol have claimed criminals involved in the illegal activity had received around £6.9m in profits and made payments of £1.7m to those taking part.
Director of Europol Rob Wainwright said in a press conference: "This is the work of a suspected organised crime syndicate based in Asia and operated with criminal networks around Europe.
"It is clear to us this is the biggest ever investigation into suspected match-fixing in Europe. It has yielded major results which we think have uncovered a big problem for the integrity of football in Europe. We have uncovered an extensive criminal network."
The investigation was carried out over 18 months.
