According to this recent article by The Telegraph: China vs. S. Korea, Japan vs. S. Korea, and Iran vs. Saudi Arabia are among the 20 fiercest international football rivalries. However, I think that's pretty historical and political. Or maybe these sides have not been able to face each other as much as fans would have desired. Which match ups do you guys think are the fiercest football rivalries in Asia or have potential to be one? (AFC has changed a bit with Australia joining in and Saudi going into a coma.) Keep the banters fruitful but friendly. Refrain from personal insults.
