My dark horse is Belgium. The have an easy group. Argentina has poor goalkeeping and not the best defense but probably the most prolific attack in the world cup. Brazil is solid all around. No European team has ever one the world cup in South America for 2 reasons: humidity and time change. The humidity plays a huge role though because there is practically no humidity in Europe so it drains them. Spain is still the best team in the world, but I don't think they will be able to cope with the weather.
