The frequency of use is not the point of GLT. It is a back-up system, a support infrastructure, whose purpose is to help minimise inconsistencies and serve justice when called upon. The cost is a small price to pay for the transformative effect it could have upon the one game where it matters. Early in the 2009/10 season Crystal Palace had a goal ruled out against Bristol City after it had actually gone in the net and bounced out.1 They lost two points because neither the referee nor the assistant referee saw the ball go in the net, and if Palace had not beaten Sheffield Wednesday on the final day of the season, they would have been relegated because of it. Given Palaces' dire financial situation, this would almost certainly have resulted in the club being liquidated. Just because it is rare, that does not mean it is not valuable.  1 Palace denied replay over ‘goal’, BBC Sport, 27th August 2009, accessed 25/05/11
