As odd as it may sound, Chile will be Spain's biggest opponent in the group stages of the 2014 World Cup.
The Chileans have proven to be a very promising side and could even be one of the biggest surprises of the tournament. They defend well, build up play and are extremely strong in attack. To put it simply, Chile can do it all.
Chile really can beat you in many different ways. Their unpredictability will make them a difficult opponent for Spain and their strength and speed will likely put the reigning champions on the back foot a few times.
The South Americans have only lost two matches in 2013 with their last defeat coming at the hands of Brazil in a friendly.
However, Chile has not been playing easy matches this year.
In November, the Chileans defeated England in a friendly match by the score of 2-0 which opened the eyes of the footballing world. They have showed that they are a force to be reckoned with.
Chile also played Spain in September with the match ending in a 2-2 draw. If that match was any indication of how they will test the reigning champions in the group stages, Spain might have a real challenge on their hands.
Led by Alexis Sánchez and Arturo Vidal, Chile is full of attacking talent. Gary Medel also gives the midfield real strength and an identity of not giving opponents anything easy.
Chile are arguably the favorites to finish second in the group, but they will surely give Spain a challenge.
