PGMOL, the referees organisation, have acknowledged that the Video Assistant Referee in Tottenham Hotspur's 2-1 win over Liverpool made a "significant error" in not overturning a decision that awarded Luis Diaz as offside after scoring in the first half of the match.
In the 35th minute, with score 0-0, Diaz was sent clear and put the ball into the net, only to see the offside flag raised. The VAR, Darren England, did not overrule the decision.
After the match, PGMOL issued the following statement.
"PGMOL acknowledge a significant human error occurred during the first half of Tottenham Hotspur v Liverpool.
"The goal by Luiz 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."
