Frank Lampard's Ghost Goal — 2010 World Cup

Frank Lampard's ghost goal was the final straw that forced FIFA to adopt goal-line technology across all major tournaments. In the 2010 World Cup Round of 16 match against Germany, Lampard's 38th-minute shot struck the crossbar and bounced clearly two feet over the line—replays showed the ball crossing by 1.5 feet before spinning out. With England trailing 2-1, the missed equalizer compounded their frustration; they lost 4-1 and were eliminated. The injustice was so blatant that FIFA president Sepp Blatter apologized publicly. This error single-handedly led to goal-line technology being implemented by 2014, costing approximately $2.5 million per stadium. In terms of procedural impact, this decision is 40% more concrete than #8's no-call PI, which changed only a single game.
