Australia and Indonesia will be meeting at the AFC Asian Cup  for the first time and have not faced off against one another since a qualifier for the 2011 tournament in Brisbane in 2010, which the Socceroos won through a solitary goal from Mark Milligan.

Arnold’s team will go into the game as favourites but the former Sydney FC coach is wary of Shin Tae-yong’s side after their performances in the group phase, where the Indonesians notched up a 1-0 win over Vietnam.

“Indonesia have shown what the competition is about and the strength of the competition,” said Arnold. “Every time we go on the pitch and prepare for a game we prepare for a tough game and we expect that tomorrow.

“We have to be at our best and we can’t have any slip up in the mental side of it.

“It's not a David v Goliath battle. It's two teams that will go out there and give it their best. They've shown in this competition so far, against Japan and against Iraq, how strong they are, and obviously they won against Vietnam.

“We've watched all the games, we've done all our research, and we're planning ourselves to win the game.”

Indonesia will be appearing in the knockout rounds of the AFC Asian Cup for the first time with the country making their first appearance since 2007, and coach Shin acknowledged the difficulties his side will face against a team 121 places higher in the world rankings.

“Tomorrow’s match for us is never going to be easy, especially because the Australia team is one of the strongest teams in the Asian Cup,” said the former Korea Republic international, who finished his playing career with A-League side Queensland Roar.

“They’ve got strength and power and I think in those aspects Australia is probably the strongest in this competition.

“We’re going to play with a strong mentality. We will never give up. We’re going to focus on the match until the referee blows the whistle after 90 minutes. We’re not going to have any regrets and we’re going to do our best.”
