Former Premier League referee Keith Hackett said VAR got it badly wrong in Tottenham's 2-1 Premier League defeat at Chelsea on Saturday.
Referee Michael Oliver deemed that Giovani Lo Celso's rash challenge on Chelsea defender Cesar Azpilicueta at Stamford Bridge did not warrant a red card and VAR upheld his decision.
According to BT Sport, officials at the VAR hub in London later admitted the decision was wrong and Hackett took to Twitter to demand those responsible for VAR decisions "update" themselves on the laws of the game.
"Come on David Coote VAR," Hackett said. "That is a red card every day. It's not a difficult decision. Lo Celso should have received a red card.
"Now I want to know who is the person at the centre of the PGMOL (Professional Game Match Officials Board Limited) statement. I suggest that he goes to https://bsmedia.business-standard.comtheifab.com and updates himself on LOTG (laws of the game)."
Chelsea manager Frank Lampard, speaking about the tackle, told BT Sport: "I hate to call for red cards but that is a leg-breaker. I am not saying about referees on the spot. VAR is here to clear things up and it is not good enough."
