Saudi Arabia shocked the world with a 2-1 victory over La Albiceleste in what was, statistically speaking, one of the biggest upsets ever.

Brazil vs. Germany 7-1, 2014

Yet, 2nd ranked Germany squashed their 3rd-ranked Brazil opponents, scoring four humiliating goals in six minutes. The game turned out to be a national embarrassment for the hosts, especially for a game that promised to be intensely competitive.
