Jorge Larrionda, the referee who failed to see a shot by England's Frank Lampard cross the goal line at the 2010 World Cup, says he's in favor of using goal-line technology (GLT) to aid match officials. Uruguayan official was running the middle during England's 4-1 loss to Germany in the first round that featured a Lampard shot clearly landing beyond the goal line after hitting the crossbar but not ruled a goal.

Hired by FIFA to help train top-flight referees, Larrionda admits he suffered through a difficult World Cup. Yet he believes his error led to a positive change; the convincing of FIFA president Sepp Blatter that GLT was needed.

"It's for the global benefit of the sport,'' Larrionda regarding the use of technology. "It's all about protecting the game and to have credible soccer."

The Dec. 6-16 FIFA Club World Cup in Japan will test both the systems approved by FIFA: the British system Hawk-Eye that uses multiple cameras to track the ball, and the German-Danish project GoalRef that uses magnetic sensors in the goal frame to monitor a special ball.
