Rio Ferdinand admitted to being left 'confused' by VAR after two contentious penalty decisions went against Arsenal in their 2-1 defeat to Manchester City.
They were denied a spot-kick during the first-half when Martin Odegaard went over in the box when challenged by City goalkeeper Ederson.
VAR official Jarred Gillett took a long look at replays before agreeing with on-field referee Stuart Attwell that Ederson had got a toe to the ball before his contact with Odegaard. Attwell didn't consult the pitchside screen on that occasion.
And Arsenal's sense of injustice only deepened in the second-half when Bernardo Silva was brought down by Granit Xhaka's shirt tug, with Attwell this time overturning his initial 'no penalty' decision after consulting the VAR monitor.
