Very happy and can't believe it is finally being introduced . Showed us once again how much referees suck . It seems to go smooth and as we go further i am sure there will be even more accurate , smoother and faster decisions with video replay technology help .

My only concern is during what plays exactly are they allowed to use it?
During Chile Cameroon match Cameroon scored a perfectly valid goal and it was ruled off due to a "foul" on Vidal. I don't understand why it wasn't replayed to show the play over. Also the use on Chiles first goal was good. My only complaint is that it kinda ruins the mood waiting to see if a goal os valid or not. But as it gets used more I'm sure it will be more fluid.

That is a good question. I don't know answer to that .

I agree that it is still slow and a bit strange that it does take that long to figure the decision out . LOL I do it without replay , live :D

Nothing but helpful so far, but yeah need to find out the exact rules when it can be used.
