Gabriel Jesus seemed to have won the tie after smashing a shot into the back of the net from a corner. However, it was ruled out due to a handball from Aymeric Laporte in the build-up, with officials at Stockley Park spotting the infringement.
City were furious with the decision as Spurs thanked their lucky stars.
But Gabriel could not help himself from approaching the ref at the final whistle to give him a piece of his mind.
The striker launched into a verbal blast at the official before being ushered away by opponent Harry Kane.
But footage caught Gabriel saying “VAR is s***" before turning towards the dressing room.
