As a Korean, I want to root for South Korean team, but after watching their recent game vs. Sweden, I lost hope.
Also their football association is very corrupt and in denial.
I'm rooting for Iceland right now though. They are quite good, and did you know that the team members have different jobs? (their head coach is a part-time dentist!)
I personally think Portugal will win, given that their team is in excellent shape with Ronaldo in it.
