They will be introduced immediately following Luis Diaz’s disallowed goal as Liverpool lost 2-1 at Tottenham.
The Professional Game Match Officials Limited (PGMOL) later admitted that a “significant human error” had taken place.
Darren England, who was on VAR duties for the game, mistakenly thought that the goal had been awarded by the on-field team so quickly said “check complete” to confirm that Diaz was onside.
But the on-field team took that to mean that their original call of offside had been correct and play restarted, prompting a massive furore afterwards.
PGMOL has now noted that the fresh guidance will “enhance the clarity of communication between the referee and the VAR team in relation to on-field decisions”.
VARs will now confirm the outcome of the checking process with the assistant VAR before confirming the final decision to the on-field officials, to prevent a repeat of what happened with Diaz
