With all respect, threads like this always might tend to generate innecesary discussion, some people votes with their head, others vote for their heart. I respect serbian team, a lot, but i think there are teams stronger than them, however a good managerial work can compensate many weakneses, so why not?
If i would vote with my heart, Argentina is a candidate, it always is after all. But many things changed this season, new engine made us weaker than before, and things in our lives are different too. I will vote with my head: i picked China, but i think that Thailand have a big chance too.
