The two nations will avoid each other if they make progress from the third round.

The top-two teams from each of the five groups which are currently playing in the third round (last Match Day is June 22, 2008) qualify for the final phase which runs through September 6, 2008, to June 17, 2009.

1) Australia

2) South Korea

3) Iran

4) Saudi Arabia and Japan (joint-fourth)

If all the five top seeds qualify for the fourth round, Japan and Saudi Arabia, who are tied fourth, will be separated by a draw.
