Football is undoubtedly the most popular sport around the world and many great teams have experienced wild upsets throughout their histories. There have been a number of games that went against the favorites because of a particular set of circumstances but never again did such a dark horse team go on to win not just a game but also a major international tournament. 
Available at odds of up to 250–1 and having never won a game in any major tournament before, Greece managed to win the 2004 UEFA European Championship after eliminating a series of soccer’s superpowers one after the other including Spain, Russia, the reigning champions France, the Czech Republic, and host nation Portugal in the final.
