I'm watching the highlights.
OK it's a pen. VAR gets it "right". The ref waits for a word in his ear, play moves 70 yards... he blows, goes, watches the tape... it's a pen...
In real time it's a good shout but one of those that's easily missed.
So, yeah it's good use of VAR.
But (in addition to any practical criticisms) it's not what I want. It's not football. It's never going to be football in 999/1000 matches. The premier leagues in most countries will never be able to afford it or be able to staff it with competent enough officials. 2nd divisions, elite youth, never.
It's a toy. A billionaire's play thing. Leaves me feeling a bit hollow.
