#3 Panama
Panama, a country with 4 million people, broke the hearts of 322 million Americans when they qualified for World Cup at USA's expense. Panama owe a certain part of their accomplishment to another tiny Caribbean nation i.e. Trinidad and Tobago for the way they made the US bite the dust on the final day of the campaign.
Panama have been drawn alongside England, Belgium and Tunisia. They need to display outstanding football in order to advance to the knockout stage when they start their first World Cup campaign by facing the mighty Belgium on 18th June in Sochi.
For a team who defied the odds and qualified for the World Cup, you can't really rule anything out when the group stages begin as they really have nothing to lose.
