Referees' chief Howard Webb says steps have been taken to avoid a repeat of the controversy surrounding Luis Diaz's disallowed goal for Liverpool against Tottenham.
Liverpool lost the game 2-1.
"We've put quite a lot of steps in place to ensure the error that we saw doesn't happen again," Webb told Match Officials: Mic'd Up.
In audio recordings of discussions between the match officials made public by referees' body the Professional Game Match Officials Limited (PGMOL), England says the check is "perfect" before swearing when he realises a mistake has been made.
Webb said VAR had "fallen short" on this occasion and the PGMOL needed to act, with new VAR communication guidelines being applied since then.
