I thought it was the ref who pulled it back, and the guy behind the goal who let play carry on. What's wrong with using Hawkeye... I just don't get it
You are aware that several systems are being tested at the moment and therefore haven't yet been proven to accurate although one hopes they will. However, they are only being tested to determine whether a goal is scored or not,not if the ball goes over the goal line for a corner or goal kick.
I think the goal line officials are there purely for goal line decisions and for nothing else
I think someone else has already mentioned it but it is also any incidents in the penalty area. They inform the ref via a mike and make no gestures.
