Hand of God goal by Diego Maradona

Probably, you know the most controversial goal in one World Cup match. So-called "Hand of God" goal scored by Diego Armando Maradona in a quarter-final between Argentina and England (2-1) at the 1986 World Cup in Mexico. His second goal at the same match was voted as the Goal of the Century by FIFA.com voters in 2002.

Maradona won the Golden Ball as the best player of the tournament and Argentina win the 1986 World Cup with a victory over West Germany in the final match.

Here is the description of the goal from Wikipedia:

Six minutes into the second half, Maradona cut inside from the right flank and played a diagonal low pass to the edge of the area to team-mate Jorge Valdano and continued his run in the hope of a one-two movement. Maradona's pass, however, was played slightly behind Valdano and reached England's Steve Hodge, the left midfielder who had dropped back to defend.

Hodge, tried to hook the ball clear but miscued it. The ball screwed off his foot and into the penalty area, toward Maradona, who had continued his run. England goalkeeper Peter Shilton came out of his goal to punch the ball clear, with his considerable height (1.85 m), making him clear favourite to beat Maradona (1.65 m). However, Maradona reached it first, with the outside of his left fist. The ball went into the goal, and the referee (Tunisian Ali Bin Nasser), not having seen the infringement, allowed the goal.

After the match, Maradona said that the goal was scored:

...a little with the head of Maradona and a little with the hand of God.
