I HAVE (mostly) NO BIAS. The list is more or less accurate although I would switch Belgium and Ecuador and move England two more places up. Even in Brazil's current form is not good, it's still THEIR world cup, they'll be one of the teams to watch out for. COLOMBIA and BELGIUM will probably be the dark horses in the world cup in my opinion.

NOTE:: I didn't make this list. I just copied and pasted the rankings for those who aren't interested or are too lazy to read the whole article.
