Did you catch the disallowed England goal today. Thats rekindled the whole technology debate. I'm still against it. Yes, I did...I watched both games today. (When I included my comment, "based on what happened in today's games", I was referring to the disallowed goal). The ball clearly bounced behind the goal/end line.
There are no valid arguments against a replay for (at the very least) disputed goals.
I'll continue to say it: the FIFA World Cup is a flawed product.
