To see the Socceroos train overnight...
   

Serbia suffered a shock defeat to New Zealand in Austria on Saturday, a result All Whites coach Ricki Herbert described as the best in his nation's history.

But the Australians, who have been in camp in Johannesburg for nearly a week while the rest of their opponents are still over a week from arriving, are not reading too much into the current form of Serbia.

"I think it's a bit tough to judge from that game," Mark Bresciano said after watching the All Whites edge out the world No.15 1-0 in Klagenfurt. 

"It's still preparation. If you look at some of our games we played it wasn't the best but this is all about preparation for the World Cup."

Jason Culina said he has a very high opinion of Serbia and thinks the result is more a measure of how much New Zealand has improved.

"New Zealand showed against us that they are a very good team and they can play some very good football," he said. "They are very physical.

"The Serbians I think are a great team and come World Cup time will be big challenge for us."

Fellow group D rival Germany impressed with a 3-0 win over Hungary at the weekend, while Ghana takes on Netherlands on Wednesday, their first match since Michael Essien was ruled out of the tournament through injury.

The Socceroos are still undertaking a heavy training workload in order to build fitness ahead of the tournament and see the Denmark game as another step in that preparation.

Culina added: "It's probably more of a training hit out.

"We do take it very seriously and we want to win, we go out every game to win. We haven't spoken about that game as yet, but its about fine tuning our game and our fitness."
