Socceroos switch World Cup focus: Irvine

The Socceroos have already switched focus after rapidly digesting the harsh lessons from their schooling by France, midfielder Jackson Irvine has said.

After being hammered 4-1 by France in their World Cup opener, the Australians meet Tunisia on Saturday.

Another loss will consign the Socceroos to yet another exit at the group stage - the fifth time in six appearance at the cup finals.

Irvine says the French belting was a valuable lesson for the Socceroos, but not one to overly dwell on.

"The mentality has to be to move on quickly," Irvine told reporters on Wednesday.

"Obviously where we can improve, what we did well, and what we can take forward.

"But generally speaking the mentality has already switched into focusing on the next game and using last night as a platform to build for Saturday rather than over-thinking how that (France) game went."

Key midfield cog Ajdin Hrustic is likely to return for the clash against Tunisia, who drew with Denmark in their cup opener.

Hrustic hasn't played since October 3 because of an ankle injury but coach Graham Arnold was ready to pitch the attacking midfielder into action against France from the bench.

But with Australia's hopes of an upset win dashed, Hrustic remained on the sidelines.

"He's a quality player, obviously we want him out on the pitch as soon as he is available," Irvine said.

"I am sure he will have a big role to play in these next couple of games."

The Australian expect Tunisia, renowned for defensive intensity, to present an entirely different challenge than France's attacking flair.

"A very different opposition, the game will flow in a very different way," Irvine said.

"Against a team that can play so compact ... you are going to have to find different ways to create chances.

"We have got the quality of players who can play in those areas out wide or in between lines and create chances to score goals.

"We will look at where are the best areas to hurt them but not much changes within the framework that we're always trying to do."
