Fans were left fuming after Gordon's harsh challenge on Van Dijk as they criticised the England international on social media.
An Arsenal fan handle named DJ wrote on X: "Not sure how anyone can watch that tackle and come to the conclusion that Gordon or Newcastle have been hard done by. Nasty tackle, genuinely could’ve snapped his leg in half."
Leo posted on X: "Uup, too much adrenaline, too little thought. They were just aggressive to hype the crowd, with little to nothing to it. Red card right call for Gordon."
A fan named haydon wrote: "The gordon tackle is a red but the Gravenberch tackle not going to VAR earlier on is an interesting double standard."
Calum Vine posted: "Really poor from Gordon. Thought he was unlucky not to score in the first half. Liverpool got the game in their hands now, can not see them not winning now."
Adam Brooks labelled Gordon's tackle as 'madness', as he wrote: "Newcastle are always a very physical team. Often getting away with being a little too physical. Madness from Gordon. Early bath, young man."
