Group E - Switzerland vs Ecuador
Where - Estádio Nacional de Brasília, Brasília
When - Sunday 15th June, 12pm EST / 5pm BST
The Swiss are the seeded team in Group E on the backs of an impressive qualification under wily manager Ottmar Hitzfield. They might have benefited from the much-maligned FIFA rankings, but Switzerland are a dangerous team under playmakers Gokhan Inler and Granit Xhaka, and a pair of tireless fullbacks in Ricardo Rodriquez and Stephan Lichtsteiner.
Ecuador for their part will be out to prove that they do belong on the world stage and are not just here thanks to the altitude advantage they had with playing their home fixtures in the rare air of Quito (22 of 24 points at home, 3 of 24 away). Antonio Valencia is one of the better pure wingers at the tournament, while Jefferson Montero is a midfielder to keep an eye on.
Group E - France vs Honduras
Where - Estádio José Pinheiro Borba, Porto Alegre
When - Sunday 15th June, 3pm EST / 8pm BST
This France side are far removed from the chaos that have plagued their last few editions, thanks to coach Didier Deschamps carefully weeding out elements that were considered disruptive. While losing Franck Ribery for the tournament will hurt them, it does make them a more cohesive unit. With budding stars like Paul Pogba and Antoine Griezmann to provide service for Karim Benzema, and underrated players like Mathieu Valbuena and Johan Cabaye pulling the strings, the French could be ready for a breakout tournament.
Honduras rattled England in a friendly last week with their out-and-out physical approach, and could rely on that again to shake up the French. Their strengths are upfront, with Carlos Costly and Jerry Bengtson expected to provide the goals. France doesn't have much experience with Ribery out and could struggle if Honduras scores first.
Group F - Argentina vs Bosnia and Herzegovina
Where - Estadio Jornalista Mário Filho (Maracanã), Rio de Janeiro
When - Sunday 15th June, 6pm EST / 11pm BST
This should be the highlight game of the day.
Argentina have enjoyed World Cup success in the past, but have flattered to deceive in recent tournaments. Superstar Lionel Messi has not been as influential in the blue-and-white stripes as he has at Barcelona, and has a point or two to prove. Aside from him, stars abound in the forward ranks with Gonzalo Higuain, Sergio Aguero and Angel di Maria also playing. Question marks remain in the center of defence, but the though is that they should be outscore themselves out of trouble especially in the group stages.
Making their maiden appearance at the world stage, Bosnia are out to prove that they too do belong and aren't just making up the numbers. It is worth noting that on backs of attack-minded players like Edin Dzeko, Miralem Pjanic and Senad Lulic, Bosnia scored 30 times in just ten games during the World Cup qualifiers.
