They would then fight out top spot with Germany in the final Group D match.Speaking for the Black Stars, midfielder Ibrahim Ayew heaped pressure on the Socceroos, suggesting, "Australia must know we are going to attack and attack them.""We know they have some weak sides and we will take advantage. We are young and we are really going to use our pace."Everything is focused now on the Australian game. It is the most important thing in the world. When we win against them we will be in the next round."Ghana defender Hans Sarpei alluded to his team's success over Serbia as a sign of future success.
