A couple of investigations have begun about Cameroon having fixed their matches at the world cup. http://www.nytimes.com/2014/07/02/s...usations-against-its-world-cup-team.html?_r=0
I saw a piece about this yesterday on SKY news, and the reporter had been to the Cameroon Football association offices who say they will carry out an investigation. The report commented that when he went to the offices there was one man and a goat there, and he doubted they could carry out such and investigation fairly.
And yet there's no talk of England's defeats being put down to match fixing. At least Cameroon (allegedly) had a reason for losing.
