I believe that a system should be implemented similar to what they have in Ice Hockey, if the puck goes in a little buzzer/light thing over the goal like goes off and notifies you that the ball has crossed the line. In a time with hi tech video technology it is essential that football upgrades into goal line technology. It would avoid terrible decisions and would actually make the game fairer in my opinion. I realise that people think it would be bad for the game and it would waste time. But if you implement the right technology it won't waste any time, all that will happen is a little light goes off when the ball crosses the line, hell they could make football more colourful by having the woodwork change colour when the ball goes in.
Now you are all allowed to have an opinion on this and most of you will probably disagree with me but I think it is essential that everybody sees what I believe is the easiest way to take Football to the next level. I am not being bitter about Liverpool losing the FA Cup Final either, I just believe that this is a good example of how goal-line technology would be beneficial.
