In association football, a ghost goal (or phantom goal) is either a goal wrongly awarded despite the ball not having crossed the goal line, or a goal wrongly not given despite the ball having crossed the line. In an attempt to combat ghost goals, rules allowing goal-line technology (GLT) were passed by the International Football Association Board in 2012 and have consequently been introduced for some football competitions, including the FIFA World Cup, FIFA Club World Cup and Premier League. The video assistant referee (VAR), introduced in 2018, provides an alternative system to GLT, and is cheaper to introduce and operate than the FIFA qualified GLT systems.
