Head of referees, Howard Webb, has stated that measures have been implemented to prevent a recurrence of the VAR mistake that led to a valid Liverpool goal against Tottenham Hotspur being incorrectly disallowed.

The Professional Game Match Officials Limited (PGMOL) acknowledged that VAR made an erroneous offside ruling when Luis Diaz scored what should have been the first goal in Liverpool's 2-1 defeat.

"Having seen what happened in Spurs vs. Liverpool, we analysed the situation and had a look at what we could do better to put some safeguards in place," Webb told the TV programme Match Officials. Mic'd Up.

"We worked hard over the subsequent days to look at what we needed to do to put in those safeguards around the communication to avoid that sort of thing happening."

In response to why the referee couldn't halt the game after play had resumed, Howard Webb explained that by the time both the VAR and his assistant recognised the error, it had reached a point where it was no longer feasible to intervene.

"They recognised that the laws of the game, set by FIFA and the IFAB, doesn't allow that," Webb added.

"There's obviously a process in place that sits in the laws of the game... And it doesn't allow you to go back to those circumstances.
