I’m not so sure the rules were followed, it has a clause that if it’s a clear offside or the ball is on the wing to flag it, it was one of the clearest offsides in real time you will ever see. There was a 0.0% chance of that ever being allowed had the ball gone in.
If that’s not something the linesperson is going to call, then we might as well say there is no point of having someone run up and down the line anymore in games with VAR. Just put a ref in each half with the eye in the sky acting as the third.
