JAKARTA, Indonesia _ After watching South Korea squeeze into the Asian Cup quarterfinals with a 1-0 win over Indonesia in Jakarta, under-fire coach Pim Verbeek turned his attention immediately to the knockout stage.

Kim Jung-woo's first-half strike Wednesday was enough for victory for the South Koreans, who were helped greatly by Saudi Arabia's 4-0 win over Bahrain in Palembang.

South Korea started the game in last place with one point from its opening two games and was dependent on other results in Group D.

The Taeguk Warriors finish second in Group D on four points, three behind winners Saudi Arabia. Indonesia and Bahrain collected three points each.

"We knew we had to win. We created many chances and we are ready for the next round," Verbeek said. "We did what we had to do and gave almost no chances away. We played a good game. I am happy."

The result meant disappointment for Indonesia and 90,000 fans in Gelora Bung Karno Stadium. A draw would have been enough for the co-hosts but their thrilling adventure in the competition ends.

"I am disappointed that we can't continue in the Asian Cup but proud," Indonesia coach Ivan Kolev said. "We fought 'til the death. From the first match until the third the players gave their best performance in what was a tough group."

Kolev said he hoped that Indonesia can use the experience as a platform to better things.

"There are so many lessons we learned," he said. "For sure, we will use these for a better Indonesian team. Hopefully, Indonesia will have a good team in the future."

After all three goals conceded in the previous two games had been the result of crosses, Indonesian coach Ivan Kolev dropped usual goalkeeper Yandri Pitoy and drafted in the taller Markus Rihihina.

The replacement was busier than his Korean counterpart in a first half that saw the two-time champions have much of the play without creating too many clear opportunities.

El will face the Group C winner in the quarterfinal in Kuala Lumpur on Sunday.

That is likely to be Iran.

"I saw Iran play against China," Verbeek said. "Of course they are one of the powers of Asian football. Let's wait and see, it will be an interesting game, whoever the opponent will be."
