Chipperfield is in goal-scoring touch with both his Swiss club-side Basel and the national team, after heading home the winner in the Socceroos opening World Cup qualifier against Uzbekistan.

While the 32-year-old wasn't expecting to see his name on the score-sheet on Wednesday night, he did reveal today that coach Pim Verbeek had made an invitation for his defenders to get up the ground and take risks.

"He likes the full backs to overlap and push forward, create the extra man and cross it in the box, whether it's Josh (Kennedy) or Timmy (Cahill) who's playing up front," he said.

"He wants the ball in the box and that's going to be our strength on Wednesday night."

Chipperfield has looked at home on the left side in both midfield and defence for Australia, but said Verbeek would most likely deploy him as a defender against Qatar.

"Pim hasn't specifically said yet, but this morning at training I played as a left full back with Dave Carney in front, so I guess that's the way he'll want us to play on Wednesday night."

The Socceroos completed a closed training session early on Monday and despite Chipperfield revealing who Verbeek used in central defence on that occasion, mystery continues to surround just who will partner Lucas Neill against Qatar.

Chippers added: "He had Spiranovic playing next to Lucas, so he didn't want to give too much away.

"I think he's going to wait to the last minute before he decides whether it's Craig Moore or Chris Coyne."

The reinstatement of Moore would see Chipperfield link up in the same backline that guided the Socceroos in the 2006 World Cup, but the veteran had no opinion on whether Moore or Coyne should get the nod.

"They're both great players," he said. "Obviously Moorey has played the World Cup, he's got a lot of experience.

"Coyney's only played a couple of games with the national team, but he's done a great job.

"Both are great players, they're both aggressive, both good in the air, it will be a tough decision for Pim to make, but whoever he picks, I'm sure they'll do a good job."

Chipperfield, who returned to the Socceroos line-up in August after a foot injury, received treatment on his back last week at training but ensured reporters he would be fit and firing for the match against Qatar.

The injury meant that the veteran wasn't a part of Australia's line-up when they easily accounted for Qatar twice in the last round of World Cup qualification.

"A couple of weeks ago I got a knock on the back and just from the flight it tightened up a little bit, but Wednesday night I should be 100 per cent," he said.

"I wasn't here for the last couple of games, so I don't know too much about them, but obviously with a new coach they'll bring some new ideas, it'll be a tough game.

"I don't think they'll be pressuring us too much when they're playing away from home, I think they'll sit back and try and play us on the counter-attack a little bit."

Chipperfield implored his compatriots not be complacent.

He added: "Of course we can't underestimate them, the last two games we won quite comfortably but it's a new game, they're leading the group at the moment with a win and a draw.

"Obviously playing at home it's an important game for us to get the win, we've just got to go out and there and treat it like every game.

"We've just got to be patient, obviously an early goal will be great, but we just can't get frustrated, we've just got to keep working away."
