At the end of the day, we've been calling for goal-line technology for years.
There are no negatives in giving the ref a look at a replay, it takes 5 seconds, 10 max to decide the right decision.
I understand people that say, "well, if you bring this in, football won't be the same, we won't have anything to talk about"
It's not like your gonna get a "was it, or wasn't it a goal" hundreds of times in one game. They happen, but they don't all happen in one game.
It should have been brought in years and years ago, when it was available....and they haven't.
I honestly feel, if it happens again, no matter what the game being played or for is. Get the team to walk of the pitch and refuse to play the game.
They'll soon introduce it then, when people take a stand against playing the football match.
