FIFA: No evidence of fixing
FIFA has said there has been no evidence of match-fixing at any World Cup match and called on a German magazine which made allegations concerning Cameroon to offer proof.
Convicted match-fixer Wilson Raj Perumal has denied that he correctly predicted Cameroon's result against Croatia to Der Spiegel magazine before the game.
Der Spiegel are standing by their report but have yet to provide definitive evidence of the Facebook discussion with a journalist.
FIFA's head of media Delia Fischer told a news conference in Rio de Janeiro: "We have requested Der Spiegel to provide us with all the communications with Perumal and any other material in order to prove the allegations they have made.
"So far we have no evidence of any match manipulation on the betting market. The media and other stakeholders should not call people's or organisation's credibility into question just for headlines.
"It is really important to make sure that information is handled with the necessary respect and care."
