You said in an earlier post: Definitely onside. Definitely cheating us.
My View:
Looked offside in real time
Looked offside but closer than I thought when I saw the Sky replay
Definitely offside (but by a fraction) when blowing up the image provide by VAR and using foot position to determine the offside line.
My other reply was to Marvin who is concerned for different reasons about the technology.
If the feet are on the pitch, I think your method works. If they are not then we have doubt.
For example if you take a video at an angle of a ball rolling along the ground into the goal, you know when it crosses the line, but if that shot is mid-air, you will have a problem when the goal comes into view.
This is just my opinion. I could well be wrong. I am concerned that VAR is reliant on having imagery that is in line with play. What are they doing when it is not? Are they guessing like we are in this thread?
