The Cameroon Football Federation is investigating allegations that that seven of the country’s players were involved in a World Cup match-fixing scandal, but FIFA poured cold water on the claims made by a German magazine Der Spiegel, Goal.com reported.

Der Spiegel said it had interviewed a convicted match-fixer who correctly predicted the score and a sending off in Cameroon’s game against Croatia at the finals in Brazil. The match-fixer said seven Cameroonian players were involved.

In three games, Cameroon conceded nine goals and scored just one against Brazil after they had already been eliminated. Towards the end of a 4-0 defeat against Croatia, defender Benoît Assou-Ekotto thrust his head into the face of team-mate Benjamin Moukandjo and the pair scuffled in front of their goal before being separated by another Cameroon player.

Earlier in that match, midfielder Alex Song was sent off for elbowing Croatia’s Mario Mandzukic in the back in an egregious off-the-ball incident that has inspired a new song from Cameroonian rapper Maahlox Le Vibeur, complete with an elbow-jab dance move.
