Stuart Attwell became the first referee to announce a VAR decision live inside a stadium in England during Tottenham's Carabao Cup semi-final first leg against Liverpool.
Dominic Solanke had thought he put the hosts ahead in the 76th minute when he capitalised on Pedro Porro's through ball before he slotted past Alisson.
However, after a lengthy VAR review, it was ruled that Solanke was ahead of Liverpool's deepest defender Trent Alexander-Arnold - and therefore the goal was subsequently ruled out.
And, in a new in-stadium trial of VAR announcements for both semi-finals in the Carabao Cup, Attwell subsequently revealed the reason for the goal being disallowed to the crowd at the Tottenham Hotspur Stadium.
