Recently I am following few teams which are doing good job and have good chance of going through into this event as outsider Morocco and Japan are teams to watch for surprises with few top teams are now heading for end of their glory days.
These two countries are countries that must be watched, and both are successful in their respective continents. Japan always gets positive results and they are also undefeated in the third round of the World Cup. I also agree about several big countries that are in a decline phase, so it's time for non-seeded countries to be able to develop and compete with other big teams.
