Formation: Brazil actually have quite a fluid formation and can change a lot within the game depending on factors such as who is in possession etc. They will likely have 4 at the back and a lone striker in Fabiano up front. The midfield 5 change around quite a lot (and thus so does the formation).
Manager: Dunga is an excellent manager. He used to play for Brazil as a defensive midfielder and won the World Cup in 1994. This is his first international assignment.
Qualification: Brazil won the South American section including their first every victory over Argentina in Argentina. It was a comfortable qualification although they only finished 1 point ahead of both Chile and Paraguay.
World Cup pedigree: Brazil have, without doubt, the best World Cup pedigree of any nation. They are the only country to play in every single World Cup. They have won it 5 times (more than any other country) - 1958, 1962, 1970, 1994 and 2002. They were second twice (1950 and 1998), third twice (1938 and 1978) and fourth once (1974).
Chance of progression from Group G: 85% - would have been higher if Portugal and Ivory Coast weren't also in the group.
Ivory Coast (C'ote D'ivoire)
Formation: Should be a 4-3-3. Three physically imposing midfielders, a lone striker and two pacy wingers (and full-backs) meant the formation almost picks itself. Providing Sven avoids the temptation to go 4-4-2.
Manager: Sven Goran Erikkson has had many domestic and international managerial appointments throughout his career and has been very successful. For example he has league and cup doubles in Sweden, Portugal and Italy. He is most famous domestically for his stint at Lazio. He also managed England at Euro 2004 and World Cups 2002 and 2006. Sven's England were knocked out of World Cup 2002 by Brazil and Euro 2004 and World Cup 2006 by Portugal so it is a quirk of fate that he should be drawn with these two countries again. He should add some structure to the flair of the Ivory Coast's game.
Qualification: Ivory Coast comfortably qualified from their group.
World Cup pedigree: Ivory Coast have only had one previous World Cup appearance in 2006. They didn't make it through the group stage after being drawn in the Group of Death with Holland, Argentina and Serbia and Montenegro. They will be hoping to go at least one better this time.
Chance of progression from Group G: 60%. Would really love them to qualify, will be a real dogfight with Portugal.
North Korea (Korea DPR)
Formation: I have read that this will be a very defensive form of a 3-3-2-2
Manager: Kim Jong-Hun.
Qualification: North Korea finished second in their final Asia qualifying group thereby gaining automatic qualification. They finished ahead of Saudi Arabia on goal difference (and 4 points behind South Korea) so it was a very tense qualifying battle.
World Cup pedigree: North Korea have only qualified for one previous World Cup - 1966. They had a famous upset 1-0 win over Italy in the group stages. They also led Portugal 3-0 in the Quarter-finals but ended up losing 5-3.
Chance of progression from Group G: 0.5% - they should finish last.
Formation: Should be a 4-3-2-1.
Manager: Carlos Queiroz - ex Manchester Utd assistant manager who has managed the Portugal team since 2008.
Qualification: Portugal only managed to finish 2nd in their qualifying group (behind Denmark) and only secured that in the very last game (enabling them to finish ahead of Sweden). They then needed to navigate a tricky playoff with Bosnia, which they achieved.
World Cup pedigree: This is Portugal's fifth World Cup only. They finished third in 1966 and fourth in 2006 but didn't get past the first round on their two other appearances in 1986 and 2002.
Chance of progression from Group G: 60%, in a dogfight with Ivory Coast, might just miss out.
