FIFA have revealed they have found "no indication of any match manipulation" by the Cameroon national team, nor from any other country at the 2014 World Cup.
The Indomitable Lions' woeful showing at the Brazil showpiece, where they finished rock bottom of Group A, was further dragged through the mud after it was claimed no fewer than seven of the squad members had been involved in cheating.
German magazine Der Spiegel had claimed convicted match-fixer Wilson Perumal had correctly predicted Cameroon's 4-0 defeat to Croatia, the match being most closely scrutinised, although he denied those claims soon after.
World football's governing body have also claimed they have been closely monitoring all games at the tournament, and that they have unearthed no evidence to support match fixing by any Cameroonian.
"We have requested from Der Spiegel all the communications with Perumal and any other material they claim to possess in order to prove the allegations they have made in public," FIFA spokeswoman Delia Fischer told reporters.
"The article has put the integrity of the FIFA World Cup in question which is a serious allegation.
"As mentioned on various occasions, FIFA has carefully monitored all 56 games to date and continue to monitor.
"So far we have found no indication of any match manipulation on the betting market in relation to any of the World Cup matches."
