Qualifying form: Topped a group that included France and remained unbeaten in the process. In eight games, Spain scored 14 and conceded just three – not bad at all.
Previous best: Winners in 2010
Key man: Andres Iniesta
The Barca man remains the first name on the Spain team sheet. He scores, he creates and he inspires the entire team. If Spain are to repeat the feat of 2010, Iniesta will be key again.
Potential wildcard: Pedro
The often underestimated little man has a very good goalscoring record at international level and will aim to climb out from under the radar in Brazil.
Qualifying form: Outstanding. Nine wins from ten, 34 goals scored and only four conceded. Finished a whopping nine points clear of second-placed Romania.
Previous best: Runners-up in 1974, 1978 and 2010.
Key man: Arjen Robben - One of the best players in the world, Robben remains a serious threat from the wing.
Wildcard: Jeremain Lens - There are question marks over the Dynamo Kiev striker's temperament, but he's a real talent capable of doing some damage.
Qualifying form: Strong. Finished third in a tight group, just behind Argentina and Colombia.
Previous best: Third place in 1962 on home soil.
Key man: Alexis Sanchez - The Barcelona man is their headline act. Quick, strong, skilful - he'll be a handful for any team in Brazil.
Potential wildcard: Arturo Vidal - This dynamic midfielder has just earned himself a new contract at Juventus, who recognise his value. He helps form a formidable Chile midfield.
Qualifying form: Not brilliant, but did enough to qualify automatically behind Japan.
Previous best: Round of 16 in 2006
Key man: Tim Cahill - After all these years, the former Everton forward remains the Socceroos' key threat. At 33, almost certainly his last World Cup, Cahill may even retire after the tournament next summer.
Potential wildcard: Dario Vidosic - This Croatian-Australian plays in Switzerland and has established himself in the Sion team. He's becoming a key man in the international setup too.
