Very likely VAR using better stuff than BT's coverage.
Picture
is from VAR
Lets not forget the priceless situation with Newcastle vs Watford, where they didn't have the footage that actually showed the handball
Every moron with a beer in his hand watching the broadcasted match could see it, but not the referee reviewing it...
Personally, I have absolutely no idea whatsoever how, after having the chance to review how VAR has been implemented in other competitions and the benefits and downsides, Mike Riley and his band of morons have managed to introduce something as useless as this. The clear and obvious error rule means that identical situations will/can still be treated differently depending on who the referee is. Like the penalty situations we've seen recently, Martial vs Crystal Palace, if the referee awards it then VAR won't overrule it, doesn't award it and VAR won't overrule that decision either. Sanchez vs Newcastle. VVD vs Newcastle. Not to mention the amount of clear and obvious errors they've managed to miss out on.
Offsides won't be up to the referee to make a call on, unless they decide to flag for offside before the goal is scored...And we're stuck with VAR trying to decide if the player is onside or offside by inches, spending ages in the process.
In it's current form, it's utter frustrating
