Joachim Low, Germany coach
We did our homework on Australia and we knew where they have problems. It was fun watching the team in lots of situations. The win was important for us as it will give us confidence. We now have the opportunity to reach the Round of 16 early if we win our second match. That's what we're aiming for.
Philipp Lahm, Germany captain
It was important for us to win our opening game. We knew we had a chance before the tournament and we showed that tonight. But there's still a long way to go. Don't forget we had a bit of luck in the first few minutes. You saw there that we're still a young team. This side has lots and lots of quality in it and we created a string of chances. We should have gone further ahead earlier than we did."
Miroslav Klose, Germany forward
I think everything came together very well. It's incredibly important for that to happen in your first game. We've earned some respect but we haven't won anything yet. As you saw, we're a very young team and we're having fun. I know what I'm capable of. I felt great tonight and I was able to do my bit.
Thomas Muller, Germany right-winger
We were well organised and didn't let the Australians put us off. You have to be happy when you win 4-0.
Bastian Schweinsteiger, Germany midfielder
The win is good for the confidence because you're a bit nervous beforehand and you don't know where you stand. We played some good football so let's hope it continues. There's only one target for us now and that's reaching the Round of 16 as quickly as possible.
Pim Verbeek, Australia coach
It was tough for us after the sending-off. It was tough enough before that. Germany were better and we have to win the next two games now. We need to learn from this. We didn't play as a team and after the first goal we had to do a bit more going forward. We need to score in the next two matches, that's for sure. We're better than we showed tonight.
Lucas Neill, Australia captain
The Germans are a very good team but we made it easy for them by conceding early. It was very difficult for us when we were 2-0 down with only ten men. There are still two games to go with six points at stake and that's what we have to focus on now.
