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.
Video assistant referee (VAR) Darren England did not overrule when Diaz was wrongly flagged offside last month.
In audio recordings of discussions between the match officials made public by the 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
