And BTW, disallowing goals like the first one is the worst aspect of VAR. It was correct to let it stand last night, because under the old rules which still apply without VAR, Barnes was level. There are (under the old rules) atill three possible states- in front, behind, level. It's only the affectation of VAR that determines "level2 is no longer a thing, or at least is measured in miillimetres.
Three things the new VAR offside rule does:
1. It disallows goals that were perfectly legal under the old rules.
2. It causes delays of 2 minutes or more before you can celebrate a goal.
3. It means linesmen can't hope to get the decision right so they have to let play carry on for some pointless and irrelevant action before they flag.
None of those things benefit football. They should go back to the old rule, look at a photo without drawing lines, stop worrying about knees being ahead of shoulders and go back to torsos being the relevant factor, and then VAR checks would take 5 seconds. Easy.
