FIFA have asked the German magazine Der Spiegel to hand over all the documents it says it has regarding the claims of convicted match-fixer Wilson Raj Perumal that Cameroon players threw their World Cup group games.
FIFA has refused to make any comment regarding the allegations that some Cameroon players fixed the results of their three Group A matches, which all ended in defeat, nor would it confirm or deny it was investigating the claims.
Ralf Mutschke, FIFA's head of security, has issued a statement casting doubt on the match-fixer's claims.
Mutschke says they've closely monitored all 56 games to date and they've found no indication of any manipulation on the betting market of any World Cup matches.
