Most Controversial World Cup Moments: From Biting to Karate Kicks

— -- World Cup fans exploded with opinions and reactions Tuesday after Uruguayan player Luis Suarez appeared to bite an Italian player on the shoulder in the last moments of their game.

Suarez was competing with Giorgio Chiellini for position in the penalty box in the 80th minute of the game when the two collided and fell to the ground. Chiellini promptly pulled down his jersey trying to show the referees a bite mark.

It's not the first time Suarez has been at the center of controversy at the World Cup.

Here is a look at some of the most shocking moments from the World Cup through the years:

In 2010, Suarez (yes, him again) touched the ball with his hands in order to deny Ghana a goal in the final minutes of overtime. He was given a red card, but Ghana went on to lose to Uruguay on penalty kicks.

2010 - Karate Kick

Also in 2010, the Netherlands' Nigel de Jong karate kicked Spain's Xabi Alonso in the chest during the final. The referee issued de Jong a yellow card, but later said it should have been red. Spain defeated the Netherlands to win the World Cup.

2006 - Headbutt

France's Zinedine Zidane famously headbutted Italy's Marco Matterazzi in the final of the 2006 World Cup. Italy went on to win the Cup in a shootout.

1990 - Spitting

The Netherlands' Frank Rijkaard spit multiple times at Germany's Rudi Voeller in 1990. Rijkaard was angered over a referee call and spit at Voeller's hair, and then later, pulled his hair and spit in his face.

1986 - Hand of God Goal

In one of the most famous World Cup goals, Argentina's Diego Maradona scored with his fist against England in what’s known as the “Hand of God” goal. England's goalie Peter Shilton had come out of the net to punch away the ball when Maradona leaped for it, striking it with his hand. The referee allowed it and Maradona later attributed to the goal to being partly made by the hand of God.

1982 - The No-Game Game

In 1982, a match between West Germany and Austria outraged fans after both teams stopped playing aggressively because they had both already made it to the next round of tournament. West Germany needed to win by one goal in order to advance -- a scoreline that also helped Austria get through to the next round. After the first West German goal, play practically ceased. The game ended 1-0, eliminating Algeria in the process.
