Ghana clash like a �knockout game� - Jurgen Klinsmann
US manager Jurgen Klinsmann believes a win against Ghana in Natal in the opening group game will define their success at the World Cup.
The Stars and Stripes are paired in Group G with the Black Stars, Portugal and Germany.
The former Germany international has tipped his native country and Portugal as the pre-tournament favourites to advance in the group.
�It�s pretty much just like a knockout game anyways,� Klinsmann told ESPN. �We know if we can get the three points (against) Ghana we put ourselves in a very good position for the next game against Portugal in Manaus, in the Amazon.�
He added: �Therefore it is very, very crucial we have a good start.�
