The VAR audio from Luis Diaz's wrongly disallowed goal for Liverpool at Tottenham has been released by the PGMOL, revealing the replay operator was the only person to immediately spot the mistake and urge the officials to stop the game.
Diaz was flagged offside after scoring but replays showed he was actually onside.
But Darren England, the VAR, mistakenly believed the on-field decision had been to award the goal, leading him to tell Simon Hooper, the referee, that the check was complete.
After England and the assistant VAR Dan Cook were alerted to their mistake by the replay operator when the goal wasn't awarded, they repeatedly said they could not intervene as the game had restarted.
"Can't do anything," said England as the replay operator asked for the game to be stopped.
In an increasingly-frantic exchange, the unnamed replay operator says: "Oli's calling in to say delay the game. The decision is onside".
It's understood that the 'Oli' referred to is Oli Kohout, the VAR Hub Operations executive.
Audio from fourth official Michael Oliver is not included in the clip.
As the replay operator continues to try to stop the game, England states "can't do anything" five more times before Cook agrees by adding: "They've restarted".
No further communication with on-field referee Hooper is included. Sky Sports has reported that Hooper was first informed of the error at half-time.
In a statement to accompany the release of the audio, the PGMOL accepted "standards fell short of expectations" and confirmed a "detailed report, including the key learnings and immediate actions taken, has been submitted to the Premier League, who have shared it with Liverpool FC and subsequently all other Premier League clubs".
According to the PGMOL, those key learnings include:
There has been widespread criticism that England and Cook were permitted to officiate in the United Arab Emirates for a match which took place hich took place just 48 hours before the Tottenham vs Liverpool game.
The PGMOL, along with the FA, pledged to review the policy to allow match officials to officiate matches outside of FIFA or UEFA appointments.
This is the transcript of what was said between the officials. The on-field referee does not hear all of the audio from the VAR room - only those comments directed to him.

Assistant VAR: "No."
VAR: "I can't do anything. I can't do anything. *Expletive*."
Sky Sports' Dermot Gallagher:
"It was a terrible mistake to make. Everyone has acknowledged that,
"It's now about the process and one of the processes is they will have to undertake from now is the VAR will have to ask the referee: 'what is the on-field decision?'
"If that little question had been asked and [Simon Hooper] said "offside" then you've got a starting point. Then you can go forward. Unfortunately, because that question wasn't asked, they were under the impression the goal had been given on the field and that's how everything unfolded."
Sky Sports News chief reporter Kaveh Solhekol:
"Listening to the audio, I keep wondering why they were in such a rush to make that decision.
"They are being put under pressure to make these decisions really quickly. When VAR was first introduced, and they were taking a long time to make these decisions, everyone was complaining about the fact it was taking too long.
"People in the stadiums didn't know what was going on either, so I think that's why they've tried to speed up the decision-making process.
"But listening to the audio, it's obvious that if you do anything at that speed, and so many people are watching and depending on your decision-making, mistakes are going to be made."
