it is a fallacy to say that if GLT cannot be applied to all levels of football it should not be applied at all. Nobody is suggesting that GLT be set up for all games down to grassroots level. Compromise is necessary in order to encourage reform within in a game whose stance on technology is anachronistic.  Also, other sports have only implemented technology in the professional sphere. They recognise that there is a massive amount of money and emotion invested in the professional game, and fairness is deserved as a reward.  If both teams know the rules, they can both play the game according to the same standard; GLT would not make teams play with different rules, it would just mean that some games are better equipped.
