Oleksandr Zinchenko was filmed on the bench in a state of anguish after being nutmegged leading to Liverpool's equalising goal against Arsenal on Sunday.
Arsenal had spent much of the second half defending for their lives under a barrage of Liverpool pressure, having allowed them back into the game on the stroke of half-time.
Mohamed Salah missed a penalty early on in the second half but wave after wave of Liverpool attack kept on coming.
Late on, Trent Alexander-Arnold managed to isolate Zinchenko on the right, nutmegging him before lifting a cross to the back post for Roberto Firmino to head beyond Aaron Ramsdale.
