'How is that a foul?' - Roy Keane disputes VAR decision on disallowed Liverpool goal

Roy Keane has said that Liverpool's first disallowed goal was incorrectly ruled out by VAR, claiming "the game has gone mad".
Liverpool thought they had doubled their lead through Firmino after 25 minutes but, after a VAR check relating to the build-up, the goal was ruled out for a foul by Van Dijk on De Gea.
