But do they use VAR or do they still trust the Linos?
The problem with those calls yesterday was that, whatever part of the body you choose, it still comes down to the whether they have actually caught the exact moment the ball is played and how accurately the virtual lines are being drawn. There's fair margin for error in those two major factors, so when it's that close that one virtual line is touching the other virtual line, then surely that doesn't count as "clear and obvious".
If it's taking beyond, say 15-20 seconds to see whether it's actually onside or not, then just go with the call on the field and get on with the game FFS. Leaving the ref holding his ear in the centre circle makes him and the system look stupid and is ruining the flow of the game.
VAR is, should be, an "Assistant" to the refereeing team on the field, letting them know when they've made a "clear and obvious" error, not to make close calls for them. If it's that close that you can't decide quickly, then forget it. Put a timer on it from the moment of the incident, after that the statute of limitations comes in.
