Liverpool fans will have been absolutely incensed at the decision-making on show from the on-pitch official John Brooks.
Tyrone Mings was only awarded a yellow card caution for a high boot challenge on Cody Gakpo, apparently opting to avoid going to the monitor to determine the precise severity of the challenge.
The release of one photo of the Dutchman online, however, with the forward lifting up his shirt to reveal several wince-inducing marks on his torso, arguably demonstrates that the referee’s call was the wrong one.
