Referees' Chief Howard Webb has addressed why VAR failed to rectify a "significant human error" that saw Luis Diaz's goal for Liverpool wrongly disallowed against Tottenham last month.
VAR Darren England did not overrule when Diaz was wrongly flagged offside as Liverpool went on to lose the game 2-1.
In the second episode of Match Officials: Mic'd Up alongside former Liverpool striker Michael Owen, Webb clarified that England and Assistant VAR Dan Cook couldn't intervene and remedy the mistake as the laws of the game, as set out by FIFA and IFAB, did not allow them.
"At that point they considered whether they could intervene to stop the game but they recognised that the laws of the game, set by FIFA and the IFAB, doesn't allow that," Webb said.
"There's obviously a process in place that sits in the laws of the game about how we use VAR to make sure it is delivered consistently throughout every league in the world.
"And it doesn't allow you to go back in those circumstances. As such they decided not to intervene.
"But I understand why that question was asked and I know that IFAB are, in fact before this incident even happened, I knew that they were going to do a full review of the laws of the game relating to the use of VAR."
