I never met Wullie, but I vividly remember the match against Flamengo in 1960 I think. Incredibly, we won 9-2 and Wullie was the right back up against the Brazilian world class left winger. Each time the Brazilian approached, he jinked right, left and back to right again. Wullie, still reacting to the first jink, caught him every time.
VAR review for exact same incident:
Celtic penalty claimVAR: definitely contact there. Penalty
other team penalty claim VAR: slight contact but not enough to go down. No penalty.
it’s still going to be judgement calls made by the same people under the same pressure. It might come in handy in non old firm games though.
It's the same pool of refs that review the VAR video, so I have zero confidence things will get any better against the OF in that regard. You'll never hear as many "no clear and obvious error" calls from any VAR other than Ibrox or Parkhead.
