How they qualified: Chile's campaign started well with 12 points from a possible 18, before three successive defeats brought about Claudio Borghi's sacking. Jorge Sampaoli was brought in and the livewire playing style he employs saw Chile pull off five victories and a draw in their last six games. (Not to mention a famous – and fully deserved – 2-0 win against England at Wembley.)
World Cup pedigree: Chile have eight World Cup finals tucked under their belts, with their best ever display coming back in 1962, when they finished third on home soil. In 1998 and 2010 they reached the last 16, but otherwise they've failed to get past the group stages.
Main man: Arturo Vidal. The Juventus midfielder is a complete player, combining physical and technical strengths that make him highly difficult to contain. A recent Champions League hat-trick for Juve showed just how rounded his game is.
One to watch: Alexis Sanchez. Revitalised under Sampaoli, the Barcelona forward will be a serious goal threat in the final third for Chile, as he showed at Wembley. Quick, strong, skilful and now settled in Spain, he could be a star in Brazil – and possibly the tournament's top scorer.
What are their chances? Their exciting brand of football, knitted together by an attacking coach and several first-class players, could catch many by surprise. Semi-finals would be a massive achievement, not least because Group B also contains the 2010 finalists, but it's not beyond this team.
