Germany manager Joachim Loew opted to rest several key players for the midweek friendly where second-half goals from David Carney and Luke Wilkshire clinched victory for the Socceroos over the world's number three ranked team.

"I think they were without Philipp Lahm, Mesut Özil and Sami Khedira,” Holman told the AZ Alkmaar website, after returning to his Dutch club following national team duty.

“But they played with guys like Mario Gomez, Miroslav Klose, Bastian Schweinsteiger, Lukas Podolski and Thomas Müller. They were no kids.”

Holman added: "It was a good week for our national team. The training was sharp and the group was keen on a good game against Germany. The 2-1 victory is a great result.

“It gives us a positive feeling towards the World Cup qualifiers in August and September.”

Holman continued: "In the first half Germany were very dominant, so we were forced to play the long ball.

“After the break we were much better in our game. We were right on top. This resulted in two fine goals from us. Ultimately, our victory was deserved.”

Holman also spoke about the effect of Australia's German boss Holger Osieck since taking over from Dutchman Pim Verbeek.

“The results are fantastic so far,” Holman said. “Osieck is popular among the group. He is strict, but gives players their freedom at the right moments. He treats us like grown men.

“Osieck is tactically very strong and gives players a lot of individual tips. The victory over Germany proves that we are on the right track under Osieck.”
