British police are reportedly looking into allegations of attempted match-fixing involving a friendly between Scotland and Nigeria to be played in London on Wednesday.
The Daily Telegraph website reported that officers from the National Crime Agency (NCA) have asked Fifa "to issue an alert over potential attempts to rig the game."
The game between Scotland and World Cup-bound Nigeria at Fulham's Craven Cottage ground is part of a string of warm-up matches ahead of the tournament in Brazil next month.
The NCA, which investigates organised crime, and Fifa both declined to comment on the report.
The report added that officials from the Scottish Football Association liaised with the NCA over the weekend after the match was “red flagged”.
A number of high profile Premier League players are believed to be taking part in tomorrow’s match at Craven Cottage. Liverpool’s Victor Moses, Chelsea’s John Obi Mikel, and Manchester United’s Darren Fletcher are all expected to play in the World Cup warm-up. There is no suggestion that any of the players are involved.
The revelation comes just hours after it was announced that football's other top governing body Uefa has signed a working agreement with Europol, which says it is involved in nine investigations of organised crime syndicates linked to match-fixing.
Europol director Rob Wainwright will share information on suspected fixing and illegal betting with Uefa and its 54 member federations.
Wainwright went on to add that match-fixing is not a major problem in European football "but we are making sure it doesn't become one."
