Ryan sticks by under-fire Postecoglou

The Socceroos suffered a 3-2 defeat to world champion Germany in a spirited encounter in Sochi on matchday one.

Ange Postecoglou's side takes on Cameroon on Friday (AEST) knowing that a defeat would put a semi-final spot beyond its reach if Germany and Chile draw in Kazan.

Australia's commitment to a more attacking style of play, even against international heavyweights, has drawn some criticism but Behich is confident his side's approach will pay dividends in St Petersburg.

"We finished the game pretty strong. We're disappointed we didn't get a result but we have a lot of positives to take out of it," said the Bursaspor player.

"What we did well, we did in patches. In the second half we pressed Germany a lot higher up and forced them long a lot of the time. In the first half we sat back a little bit more, which is not our game.

"We're confident and we'll continue to play the football that we have been doing over the last couple of years under the boss.

"We believe in the way we play and the system we play and we approach every game in the same way."

Cameroon's hopes of reaching the knockouts are also looking slim after its 2-0 opening defeat to Copa America holder Chile.

The African champion has now won only one of its last four matches and have scored just once in that run, but head coach Hugo Broos was happy with his players' efforts against an undoubtedly superior Chile side.

"We played really well at times, circulating the ball," he said. "It's true that we lacked a little bit of a threat on the Chile goal but apart from that, I'm happy.

"I'm disappointed with the result but not the performance of my players.

"I repeat what I said before the tournament: we have a young team that needs this kind of tournament. This is how you gain experience to become better."
