Beware of the big, bad ROK

Host Australia and reigning champion Japan will be keen to avoid fellow heavyweight the Republic of Korea when officials draw the groups for next year's Asian Cup at a lavish ceremony on Wednesday.

South Korea, which has reached eight World Cups in a row, lurks as a dangerous floater in the second pot of teams after temporarily falling outside Asia's top four when the seedings were decided.

Australia, four-time winner Japan, triple champion Iran and Uzbekistan make up the top tier and will be placed at the head of separate groups for the draw at the Sydney Opera House.
