The video assistant referee was unable to check whether Bukayo Saka was offside in the build-up to Gabriel Martinelli’s opener in Arsenal's win over Liverpool on Sunday due to a rare technical problem.
Martinelli opened the scoring for the Gunners inside the opening minute after being played through on goal by Martin Odegaard. But the move began when Benjamin White played in Saka down the right-hand side, when the latter may have been standing in an offside position.
Saka was running back towards the ball in an effort to stay onside when White played the ball, but Hawk-Eye, who provide the technology for the VAR system, was unable to determine definitively whether he was onside or offside. According to ESPN, Saka was out of view of all five of Hawk-Eye’s cameras which are calibrated to work out offside decisions.
