A “significant human error” occurred during Tottenham's 2-1 win over Liverpool after a Luis Diaz effort in the 34th-minute was incorrectly ruled out for offside, the Professional Game Match Officials Limited has admitted.
Spurs claimed a dramatic three points after Joel Matip turned Pedro Porro's cross into his own net in the sixth minute of stoppage time to continue the hosts' flying start under new boss Ange Postecoglou.
Referee Simon Hooper sent off Curtis Jones and Diogo Jota either side of half-time, but Liverpool were left aggrieved by the first-half decision to rule out a Diaz 34th-minute effort.
Mohamed Salah played Diaz through and the Colombian rifled into the bottom corner, but the offside flag was raised and a quick VAR check by Darren England at Stockley Park deemed the Liverpool attacker was offside.
Still images of the incident appeared to show Cristian Romero play Diaz onside and Spurs took the lead two minutes later when Son Heung-min poked home.
Cody Gakpo did level before half-time, but Matip's last-gasp own-goal inflicted a first Premier League defeat of the season on Jurgen Klopp's men.
“PGMOL acknowledge a significant human error occurred during the first half of Tottenham Hotspur v Liverpool,” a PGMOL statement read.
“The goal by Luis Diaz was disallowed for offside by the on-field team of match officials.
“This was a clear and obvious factual error and should have resulted in the goal being awarded through VAR intervention, however, the VAR failed to intervene.
“PGMOL will conduct a full review into the circumstances which led to the error.”
