Officiating is terrible in this WC, and it already affected the outcome of at least 3 matches that I can remember, Brazil-Ivory Coast, Germany-England and Argentina-Mexico, (I do not include USA for as I mentioned it might have been the right call, I gave the benefit of doubt in that case as there was no clear evidence as in the cases I mentioned) as all the allowed - disallowed goals influenced the match, nobody can predict what would have happened with the final score if the correct call had been made, but I am reluctant to use too much technology to avoid this, for example I watched some NHL games were the officials took 5 minutes or more to make the call, and I still disagreed with the call made!! But I completely agree that some measures should be implemented to try to get more calls right, Sunday was just a terrible day...
