Robertson was deemed to be in an offside position during the play, standing just a yard from Donnarumma inside the six-yard box. Although the Scotland international made no contact with the ball and attempted to duck out of its flight path, VAR confirmed that his movement was enough to interfere with the goalkeeper’s ability to play the ball. The Premier League’s Match Centre later clarified that Robertson’s proximity constituted “an obvious action which impacted an opponent’s ability to play the ball,” meaning the goal could not stand.

The decision proved divisive, particularly as Donnarumma appeared unlikely to have reached the header regardless of Robertson’s position. While City took advantage of the reprieve and doubled their lead before the interval, Liverpool’s players were left visibly frustrated — with Arne Slot animatedly remonstrating with the officials on the touchline. It was a key moment in a match where fine margins once again played a decisive role.

@Abdulba71267148 fumed: "Complete robbery."

@JonnyGibson33 explained: "He's miles away from the keeper the ball, literally moving away from the goal and then ducks. Incredible decision."

@holly82649091 claimed: "They want a title race between Arsenal and City."

@mo11salahh took shots at the inconsistency: "Bernardo Silva against Wolves last season. Robertson against city this season. Man City goal given. Liverpool goal NOT given."
