A laboured victory over a team ranked 31 places lower in Africa lifted the Indomitable Lions into the final elimination round this September and October when places at the Cup of Nations in South Africa will be up for grabs.

Cameroon were the first country to be eliminated from the 2010 World Cup in South Africa and they failed to make the 2012 Cup of Nations after finishing a distant second behind Senegal in a mini-league.
