Soccer fans across the world know the significance of the famous "Hand of God" play from Diego Maradona in the quarterfinals Argentina vs. England match from the 1986 World Cup. In what is clearly a handball, Maradona jumps for a header and doesn't seem to reach it with his head so he uses his off hand to knock the ball past the goalkeeper. This goal gave Argentina a 1-0 lead in a match that Argentina would go on to win, 2-1. 

What could've been: Had Maradona's "Hand of God" goal been called correctly his second goal dubbed the "Goal of the Century" would have been the only one scored by Argentina thus leaving the game tied after 90 minutes. We all know that in sudden death, it's anyone's game.
