Would technology improve football?
Mistakes made by officials in Sunday's World Cup ties have sparked a renewed debate about goal-line technology (GLT). Could such technology help the game?
Makers of ball tracking systems say England's disallowed World Cup goal underlined the need technology in the game. Hawk-Eye and Cairos, who make rival GLT systems, say FIFA needs to rethink its current position.
Fifa has consistently refused to entertain the idea of using GLT saying the system is not accurate enough and is too expensive. Fifa also say this technology would impact on the "universality of the game" - i.e that the game played in the World Cup has the same rules as a Sunday League game in Bradford.
But not everyone agrees. There have been numerous calls from players, managers and coaches for a number of years, prompted by a number of controversial refereeing decisions.
Do you think that goal-line technology should be used in the game? Or would it detract from the universality of football? How do you think the use of technology affects other sports?
