I don’t know who sets the cameras up for VAR use but I imagine it would be connected to whoever maintains the other VAR equipment. The problem at Anfield wasn’t a blind spot but that the camera(s) that captured the incident hadn’t been calibrated for VAR use. This image is from what they call the high tactical camera, which isn’t calibrated for VAR use.
Why there wasn’t a better placed camera that was calibrated I’ve no idea. Whether it’s an Anfield issue or ITV or whoever they contract out the camera work to?
What hasn’t been mentioned by the conspiracy brigade is that the only other time I’m aware of this problem happening is when an Arsenal goal stood against Liverpool earlier in the season at The Emirates because no camera that captured Saka out near the touchline was calibrated for VAR use.
When they eventually bring in semi automated offside technology, where every player is tracked, it’ll remove this issue.
