Serbia striker Milan Jovanovic has urged his teammates to be courageous when they go up against a very confident Germany in Port Elizabeth on Friday. The Germans thrashed Australia 4-0 in their 2010 FIFA World Cup Group D opener, while Serbia lost 1-0 to Ghana.

"Defeat has influenced our mood," said Jovanovic. "We had expected to win the match against Ghana and we are all hurt by that failure. We missed out on our aim against an inferior rival and now we are in a position where we have to get as many points as possible against better teams than us."

The 29-year-old Standard Liege star knows they will have to play at their very best if they are to upset Joachim Low's side.

"Germany were very impressive against Australia," said Jovanovic. "They have made the biggest impact at the World Cup so far. They are like a machine, they have seven players going forward. If we want to upset them, we will have to show no fear and play the best we can, because we face a better team."
