3. Geoff Hurst's goal, 1966

This is the daddy of all controversial goals and still tends to be hotly debated even now.

In the 1966 World Cup final between England and Germany, the game was tied 2-2 at the end of regulation. Eleven minutes into overtime, English striker Geoff Hurst smashed the ball towards the goal from close range inside the German box. The ball cannoned off the underside of the German bar and then back out into the penalty box.

On the play, Swiss referee Gottfried Dienst was undecided if the play was a goal or not, but Soviet linesman Tofik Bakhramov signaled to Dienst that the ball crossed the line.

According to Bakhramov's memoirs, he believed the ball had bounced back not from the crossbar, but from the net, which made the movement insignificant.
