Always Me ?
Very interesting, thanks for sharing.
When you mention the 3 second period that VAR refs need to choose whether to act on it and then show it to the main ref, I can't help but think that there is no way that the VAR refs obeyed this rule when they denied Martinelli's goal at Old Trafford. It was more than 3 seconds from the goal and back to the contested moment. The "foul" by Ødegaard on Eriksen was a slight nudge of knees and those are rarely given in regular play.
Ahh sorry, the 3 second delay is more a they will see something on the main screen, so when they look down at their VAR monitor it should be coming up on that screen. Essentially it allows them to watch the issue on the VAR Monitors across all 12(ish) camera views as it happens (sort of) So they have a chance to react.
After the event has happened and they flag it, the time it takes to review does have an SLA (not sure what it is) but it can be quite long. As we all know. Most of the time when something happens they will go through every angle to see the contact, what led up to it, intention, where the players eyes are focused etc. Then its down to the 4th official to make a decision. The Operator just provides as much footage and context as possible.
The Operators are not just working with the 4th official, we have operators who are providing replay packages and are in the ears of the broadcasters. Saying they have an interesting replay package and do they want it, there are operators who are looking at collisions and injuries and providing real time data to the medical teams (the tablets you see all the coaches and medical staff with are all showing data/footage from our operators), should the player come off because it was a nasty head injury. A lot of the time that info comes from our guys.
The GLT tech is different and thats instant. Refs have a watch and our system just says goal or no goal. Same as what we did during the worldcup with offside. No measuring rubbish. Just a call on if it was on or off. I believe that will be implemented in the Prem soon. So VAR will just be for fouls and red card decisions.
