Chile's friendly victory over England at Wembley showed the strength of this South American side. Chile finished third in their qualifying, which was missing a notable opponent as Brazil qualified automatically as hosts. However, they were only 4 points behind leaders Argentina and Lionel Messi. A lot will be said of Barcelona's Alexis Sanchez, especially after his brace at Wembley, but he's not the only player to look out for. Juventus duo Arturo Vidal and Mauricio Isla will be key in defence and midfield, while up front Wigan's Jean Beausejour will also be in the spotlight. The Chileans have two major factors in their favour, the first being among the top eight seeds and the latter that this is a South American World Cup, giving them a lot of support.
