The experienced manager has been linked with a move for Fulham and Australian goalkeeper Mark Schwarzer and he says the Aussies are a chance in South Africa.

"If I was national team coach of Germany and I had to play Australia first, I wouldn't sleep well," Wenger told Channel Nine.

"It will be interesting. Australia are tough cookies in the World Cup (and) sometimes Germany are slow starters in the big competitions.

"Maybe Australia can take advantage of that. I give them a chance against Germany.

"I wish they do (beat them) because it will make it a very interesting group."

Wenger rates Australia a 40 percent chance of knocking over the Germans and shaking up the predicted pecking order in Group D.

But German coach Joachim Low doesn't appear to be losing sleep over the up-coming contest, instead hinting fans will be the ones dozing off due to the Socceroos' defence-orientated game.

"Australia can be expected to offer anything but a great spectacle,'' Low said. "Australia is all about top organisation, incredible work-rate and almost a perfect defence.

"It's very difficult to unbalance that team. Many other nations have had a very hard time against Australia."
