Cameroon coach Paul Le Guen declared a state of emergency on his team's World Cup campaign on Friday, a day before the Africans tackle Denmark in Group E at the Loftus Versfeld stadium here. Cameroon lost 1-0 to Japan in their opening game while Denmark were beaten 2-0 by the Netherlands, meaning both sides are in desperate need of a victory to keep alive their hopes of progressing to the knock-out stages.
