Tim Cahill called it a "massive honour" to captain Australia in his home city but he promised to leave emotions aside with an Asian Cup quarter-final spot on the line. The former Premier League striker, who retains his goal-scoring knack at 35, will lead the Socceroos against Oman in Sydney on Tuesday in the absence of injured skipper Mile Jedinak. I feel that it's going to be a massive game for us ... there's a lot on the line. We just want to do our country proud and do really well Tim Cahill But the Sydney native said he would not let the occasion get to him as Australia seek the victory that could put them into the last eight, and three wins from the title. "It's amazing, I love playing for Australia regardless of which country I'm in but to play at home, in front of my hometown fans and obviously family and friends is very special," Cahill said. "But with me, not a lot of emotion comes into it when I cross that white line. I feel that it's going to be a massive game for us ... there's a lot on the line. We just want to do our country proud and do really well." Despite the loss of Jedinak, confidence is high in the Australian camp after Friday's 4-1 win over Kuwait left them on the brink of the quarter-finals. Australia will guarantee their place in the knockout stages if they win and South Korea defeat Kuwait earlier in the day. South Korea coach Uli Stielike urged his players to find a killer touch against defence-minded Kuwait as they look to secure their place in the quarter-finals. The Taeguk Warriors are far from prolific and they only defeated Oman 1-0 on Saturday, despite dominating possession in their opening group A clash. And they would have paid for their lack of goals had goalkeeper Kim Jin-hyeon not expertly tipped a header onto the crossbar at the death. Stielike said South Korea had to learn to "kill the game" and take their chances when they come. "Our problem was that during a very good phase when we came out for the second half we had 70 per cent of ball possession and we had three clear chances," Stielike said. "In that moment you have to kill the game. You have to make it 2-0 and then play the last half-an-hour quietly," the German added. In Newcastle, defending champions Japan thrashed Palestine 4-0 in their opener yesterday, giving them the perfect start in their quest for a fifth title. Yasuhito Endo, making his 149th appearance for Japan, rifled a shot into the bottom corner after eight minutes. Shinji Okazaki scored with a poacher's strike in the 25th minute, reacting with razor-sharp reflexes to head in a volley from Shinji Kagawa which looked to be fizzing wide. Keisuke Honda, Japan's bleach-blond cult hero, then stroked home a penalty just before half-time before defender Maya Yoshida nodded in a fourth as the floodgates threatened to burst open in blustery Newcastle. Meanwhile in Brisbane, a magical goal from midfielder Yaser Kasim gave Iraq a crucial 1-0 win over a 10-man Jordan. Kasim, scored the winner in the 77th minute. Taking the ball from outside the Jordan box, the 23-year-old dribbled his way past three defenders, then unleashed his shot at goal.
