WORLD CUP 2014: Which Asian Team is the Strongest?

It's out already. Everyone now knows the result of the 2014 WORLD CUP draw. Brazil as the host will be in Group A, while defending champion Spain is in group B. And to be honest, I already supported Spain even though they lost the first game to Switzerland in their opening match by 1-0. At last, my support was really NO REGRETS as they eventually had won the cup! Next year, I wish they will not win again. HAHA.
