No time to tinker as van Marwijk focuses on performance

Bert van Marwijk will shun experimentation in a friendly which could provide the first real window into how the Caltex Socceroos will shape up at the FIFA World Cup.

The Dutchman would not discuss which players he was considering for the clash with Czech Republic in St Polten, Austria on Friday (9:00pm AEST) but did reveal he had "60-70 per cent" of his starting XI in mind.

Tomi Juric is not out of the running to gain minutes after recently returning to training, while captain Mile Jedinak has joined his team-mates on the track following the Championship play-off final last weekend.

Tomi Juric is "becoming fit" after his injury scare.

That could mean Australia field a near full-strength team under van Marwijk for the first time.

While a competitive performance is expected, securing results at the NV Arena and in the final FIFA World Cup warm-up against Hungary are not priorities.

"I hope I can see a lot of things that we trained until now," van Marwijk said of his wish for Friday.

"It's always better when you get a result. The development is going quicker.

"When you lose you have to work harder, but I prefer to lose both games 5-0 and win the game against France. We have to be ready against France.

"But I don't like to lose. Never."

Van Marwijk has regularly stressed the importance of his players having the self-confidence and trust in their team-mates to make individual decisions within the tactical framework he hopes will carry Australia to the knockout stages in Russia.

That approach will be put to the test against a Czech side which has proved tricky to assess.

"We analysed them. But every game they play in a different organisation with different players, so it's difficult," he said.

"On the other side it's good because we try to learn to play in a way that we aren't dependant on the organisation of the opponent.

Much of the squad has been in camp for almost two weeks.

"We have to play in our same organisation. In the same organisation you can also have variations.

"When for example Rogic and Irvine play in the same position, it's completely different. It's the same when, for example, Mooy and Jedinak play in the same control position in the midfield.

"Then you get another type of playing but your organisation is the same."

RISDON: Everyone is desperate to impress in friendly

Key defender Trent Sainsbury could make his maiden appearance under the former Netherlands boss after missing the March friendlies through injury.

The 26-year-old, who is currently on loan at Swiss side Grasshopper Zurich, is encouraged by how the squad have responded to fresh ideas.

"Obviously it's a new message than what we've been used to but at the same time we're Aussies and we adapt to every situation very quickly," Sainsbury said.

"I suppose we have to when we're playing overseas, you have to adapt quickly.

"The new message has been absorbed very quickly."

The Caltex Socceroos' friendly against the Czech Republic kicks off at 9:00pm AEST on Friday night and will be broadcast live in Australia on FOX SPORTS 501 and Channel ONE.
