After the Socceroos played a hard fought 1-1 draw in their World Cup Qualification match against Iraq, all the talk post-game was the new 3-4-3 formation deployed by Postecoglou.

It was the first time Australia employed such a system during qualifying and the formation that featured three centre backs, four midfielders, a lone striker and two wingbacks, caught many by surprise.

Robbie Kruse, who normally plays as a winger was used as one of the wingbacks, said it was hard to be critical of the 3-4-3 system when the Socceroos have played with it on just one occasion.

“We’ve only recently just tried it so it’s difficult to judge,” he said.

“It was an enjoyable formation to play in, particularly when we had possession it was quite good but we all believe in what the boss wants to do and we have full faith in everything the coaching stuff give us.”

Kruse said the Aussies lost the ball in defence against Iraq too often, meaning they weren’t able to benefit from the new attacking system.

“It made it a lot more difficult,” he said.

“We struggled to win the physical battle with the long balls they played. It doesn’t matter what formation you’ve played if you are not wining your aerial battles it’s going to be difficult.”

For most of the World Cup Qualifiers, Australia has employed a back four in defence, but when Postecoglou changed to three centre backs against Iraq, Kruse said it wasn’t a surprise.

“The boss over the course of his career has always been known to do stuff like that,” he said.

 “He’s results in the past and his reputation speaks for itself. We all trust the coaching stuff and what their plans are. It’s still a point away from home in really difficult conditions.

“We have three out of four games at home now and we win all three at home and it should get us through.

“The coaching staff look at the bigger picture and they don’t want to just to qualify for a World Cup they actually want us to go there and achieve something. So we have full confidence in that.”

Meanwhile Socceroo striker Tomi Juric has no issue with the new formation and said the team will have enough time to get used to it for Tuesday night's qualifier at the Sydney Football Stadium.

“I don’t see why not,” he said.

 “We’re all big boys and we know what is expected and we all know how to adapt. It’s part of our job. We’re professional and a lot of boys play in big leagues around the world.

“It wasn’t easy last game, we all know that and the result showed for us that it wasn’t quite in our favour but we play now at home in front of our fans which is always delightful and great to see.

“I am sure it is going to improve now in the next game and we’ll cause a lot of problems, especially with the ball against the UAE.”
