Cameroon coach Paul Le Guen has called on his team to live up to their nickname and produce a lion-hearted performance against Denmark on Saturday night in a World Cup encounter that is crucial for both sides.

Neither nation were able to pick up anything from their opening Group E matches, with Cameroon going down 1-0 to Japan and Denmark suffering a 2-0 defeat at the hands of Holland.

That means another loss for either side at Pretoria's Loftus Versfeld stadium could spell the end of the road for the losers, depending on what happens in the earlier match between the two group leaders.
