Jamie Carragher believes officials need more technology after Tomas Soucek's controversial opener against Arsenal - with VAR unable to determine whether the ball had gone out of play before Jarrod Bowen crossed the ball back in.
West Ham secured a famous 2-0 win at title chasers Arsenal on Thursday night thanks to Soucek's goal before former Gunners defender Konstantinos Mavropanos headed home in the second half.
However, there was VAR controversy yet again in a game involving the Gunners after claims that the ball had crossed the byline before Bowen had hooked the ball across the face of goal for Soucek to prod home for the opener.
