Germany strolled to a 4-0 victory over Australia in their FIFA World Cup™ opener and winning coach Joachim Low believes his team can get even better. Goals from Lukas Podolski, Miroslav Klose, Thomas Muller and Cacau gave the Germans a great start to their campaign, while the Socceroos were left to rue not only the result but a red card for key man Tim Cahill.

"There is still room for improvement," said Low. "Our defence was excellent, they performed very well and I was very happy with our counter-attacks. But in terms of closing the space between defence and midfield, I felt sometimes we were too defensive. We will work on this."

Low nevertheless praised his young side, who dominated the match from start to finish. "It's always great to see that my team can implement my tactics on the pitch," he said. "From beginning to end, Australia was rather defensive and we had to change our attacks. I thought we did very well and we scored very nice goals. We tried to go deep down with Klose and Muller while we also kept the ball low and that created problems for Australia's defence."

Low was relieved with the win that sees his side go top of Group D. "The first match always comes with a lot of pressure," he said. "It's always important to win to get self-confidence. We can be very satisfied, happy and confident. But we have to keep our concentration. We want to reach the last 16 stage at least."

Low was impressed by Brazil-born striker Cacau, who got an easy tap-in less than two minutes after coming on as a substitute. "I think I have a range of possibilities in every position," said Low. "Cacau had a great training camp with us and I knew I had a great player coming off the bench."
