Alright, let's start at the beginning. First, they recognize that a "pass back violation" has occurred. Although the pass back to the goalkeeper was a long kick, all the conditions were met for this to be an offense:
- The ball was kicked (played by the foot) by a teammate of the goalkeeper
- The act was considered to be deliberate (not a deflection)
- The goalkeeper handles the ball directly (no interfering play from when ball was kicked)
The referee made quick eye-contact with the AR to make sure there was no contact with the ball before it entered the net and then announced that the goal was not valid. The thing I like most about this sequence of events is how the whole crew worked together. The AR flagged the initial violation, the referee allowed the quick take, the 4th official communicated with the coach and the AR silently told the Referee there was no contact as the ball when into the net. All this teamwork made it easy to get the call right.
So, what is the restart? First one to email me the correct restart will get a prize!
