GLT is used across a range of other sports  Technology has been proven to work across a wide range of sports from tennis, cricket and rugby. A survey of its implementation in the 2011 Australian Open demonstrates the impact that guaranteeing correct decisions had on several games.1 It has become a natural aid to sport. GLT would only be used on a goal decision, much like tennis uses challenges only once a rally has stopped. Football is no more fluid a sport than any of the others. If a debatable goal were scored, play would stop anyway while one team celebrates and the other protests to the officials. 1 Kelvin Goodchild, Hawk-eye: Big Impact at Crucial Moments, TennisLife Magazine, 29th January 2011, (accessed 25/05/11)
