Many big teams had difficulty in Europe, Portugal and Sweden struggled, and eventually Portugal prevailed, leaving Sweden and Ibrahimovic out of the 2010 World Cup. France struggled to get in the playoffs as well, but great playing by Gignac and Benzema helped save them a spot in the playoffs. Italy made it through, but coach Marcello Lippi was met with heavy controversy by Italian journalists for leaving Cassano out of the squad. England cruised through qualifications with new coach Fabio Capello, and Spain and the Netherlands had little trouble qualifying too.
South America
Qualified teams: Brazil, Chile, Paraguay, Argentina
Playoff team: Uruguay
Only one change in the four qualified teams from the last World Cup, Chile takes the place of Ecuador in the top four. Chile is well known for their extremely attacking play, playing with the 3-3-1-3 formation Chile seems to be one of the teams that will add spice to this upcoming World Cup. Argentina makes it in at the last with controversial comments from Maradona. It seemed that Argentina might not qualify because of the constant change in the squad.
Concacaf
Qualified teams: USA, Mexico, Honduras
Playoff team: Costa Rica

In Oceania, no direct qualification, the winner of the group of four teams goes in the playoff stages, New Zealand dominated the group with almost double points compared to New Caledonia who came second.
