Maradona's "Hand of God" (1986)

In the 1986 World Cup quarter-final between Argentina and England, Diego Maradona punched the ball into the net with his fist — and the referee allowed the goal. Maradona later said it was scored "a little with the head of Maradona and a little with the hand of God." Four minutes later he scored what FIFA named the "Goal of the Century," dribbling past five English players. The two goals in one match — one a blatant cheat, the other pure genius — encapsulate sport's eternal tension between gamesmanship and brilliance.
