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.
