In association football, goal-line technology (sometimes referred to as a Goal Decision System[1]) is a method used to determine when the ball has slightly crossed the goal line with the assistance of electronic devices and at the same time assisting the referee in awarding a goal or not. The objective of goal-line technology (GLT) is not to replace the role of the officials, but rather to support them in their decision-making. The GLT must provide a clear indication as to whether the ball has fully crossed the line, and this information will serve to assist the referee in making his final decision.[2] In the wake of controversial calls made in the Premier League, 2010 World Cup and the Euro 2012, FIFA (previously against the technology) tested potential candidates for goal-line technology. Nine systems were initially tested, but only two remain.
The first World Cup tournament to use goal-line technology was the 2014 FIFA World Cup. In a June 15, 2014 group stage match between France and Honduras, the Honduran goalkeeper Noel Valladares dropped a shot from Karim Benzema into the goal for the first World Cup goal given by the technology.
