Cody Gakpo's goal versus Aston Villa was disallowed due to Virgil van Dijk deemed to be in an offside position during the build-up.
Liverpool thought they had levelled against Unai Emery's side early on during the second half when the Dutchman bundled home from close range, only for VAR to intervene and decide the goal should not be allowed to stand.
Referred to the pitchside monitor to check the incident for a possible offside, Brooks agreed with this recommended decision and decided this strike would not stand.

The ECHO understands this is due to officials believing Van Dijk being offside after Luis Diaz's header across the box, with the subsequent touch of Ezri Konsa viewed as a deflection and not deliberate play.
This decision only added to the frustration inside Anfield after Villa defender Tyrone Mings avoided a red card for a high foot on Gakpo. VAR also reviewed this moment in the match, though the final outcome was to stick with Brooks' on-field call of a yellow card.
