Jordan Pickford escaped a red card for a calamitous lunge on Virgil van Dijk on Saturday.
Carlo Ancelotti’s side had won their opening four league fixtures ahead of the derby, and it looked as though it was going to get twice as bad after Pickford jumped into the standing leg of Van Dijk.
Although VAR were consulted, the goalkeeper would have been counting his lucky stars as the Netherlands international was adjudged to have been offside and out of active play.
Van Dijk had to be withdrawn after the incident and before Michael Keane had headed home an equalising goal, leaving Liverpool supporters fuming.
One fan wrote on Twitter: "That’s a two-legged tackle. Instant red. Am I missing something?"
With a second adding: "How is Pickford still on the pitch? And with the benefit of VAR? That’s a straight red, no question. The fact that it was offside is irrelevant. Dangerous play, red card!"
And a third saying: "I find it disgusting how he didn't even get a card."
According to the law, players are responsible for their actions throughout the game, no matter the offence.
Therefore, VAR should have told referee Michael Oliver to dismiss Pickford, though it is believed David Coote did not check for the red card - and only the offside.
Whether or not the penalty would have been awarded is a different matter - and will have been dependent on when Oliver blew his whistle for the offside, confirming whether the ball was in play or not.
