Australia coach Ange Postecoglou on Friday warned South Korea to expect a backlash from his snarling, snapping Socceroos when the teams clash in the Asian Cup final.

The hosts were beaten 1-0 by the Koreans earlier in the tournament to finish as group runners-up, but Postecoglou insisted that upset two weeks ago would count for nothing in front of 80,000 fans on Saturday in Sydney.

"No negatives came out of it," he said, flanked by skipper Mile Jedinak, who missed that game through injury. "We finished second in the group but it didn't really cost us too much.

"The most important thing is that we left that game knowing if we play our best we can certainly match the Korea team.

"It will be up to them to try to stop us scoring goals -- we'll just do what we've been doing," added Postecoglou, whose side have been the most prolific of the tournament to date, finding the net 12 times in five games, Tim Cahill leading the way with three.

"It's proven successful so far and we'll continue to do that. There won't be any secrets about how we go about it tomorrow. We'll take the game to our opponents and put pressure on them as we have in every game."

Australia's irresistible force will collide with an immovable object in South Korea, who are yet to concede at the Asian Cup, as the tournament's most prolific attack meets its best defence.

And Postecoglou, who faced criticism for resting several starters, including talisman Cahill, for the Group A meeting with the Koreans, predicted that it would come down to who flinches first -- and he backed his side to come out on top.

"Previous records go out the window," he said with the Socceroos on the brink of a first title since defecting from Oceania to join the Asian confederation in 2006. "The last game won't have any great bearing on it.

"It will be the team able to play their game the best on the day and to deal with whatever may happen, because one thing I know is (finals) never go to script.

"Sometimes the most experienced players freeze on big days but there's been nothing I've seen to suggest the occasion will get to anyone."

Postecoglou, awaiting the result of a late fitness test on defender Ivan Franjic, refused to be drawn on the threat posed by South Korea's mercurial forward Son Heung-Min, saying their opponents had other potential match-winners.

"He's a quality player," he said of the Bayer Leverkusen star. "But he's not the only one. Korea are a very good side and the reason they're in the final is that collectively they've been more consistent than other teams."

Jedinak described Saturday's final as one of the biggest games of his career.

"It's right up there," said the Crystal Palace midfielder. "Home final, in your home city -- it's got to be number one doesn't it? Winning would mean everything."
