It was a collision between Andy Robertson and a linesman yesterday in the match between Liverpool and Arsenal that made headlines more than anything else.
Arsenal looked to be in control of the game, too. The Gunners raced into a 2-0 lead against the Reds – courtesy of Gabriels Martinelli and Jesus – with Mikel Arteta's side starting the brighter of the two sides. But when Granit Xhaka clashed with Trent Alexander-Arnold just before the end of the first half, the Anfield crowd woke up.
