Goal line technology has to come into the game at the highest levels, where goalposts can contain the equipment or TV company cameras can be postioned. What concerns me is how are the LOAFs going to be changed to accommodate reviewing TV replays - do you stop the game if the ball is still in play? Instantly, or after a few more seconds to see if a goal is scored anyway?
This isn't just about the money in the game, it's about a fundamental change in the laws. FIFA have got a headache!
Cairnsy must have been sure it was over the line to give it, but then he should've flagged it to leave no doubt. It's like giving a penalty, if you're going to give one (as an AR) then give it 100%!
