Chelsea vs Arsenal: How VAR was used
VAR was used several times during Arsenal's 0-0 draw at Chelsea in the Carabao Cup on Wednesday and the consensus is that it succeeded.
The system was used twice in the first half, first for a shove by Calum Chambers on Cesar Azpilicueta in the penalty area, which resulted in Martin Atkinson speaking to the pair. Then, later in the half, Ainsley Maitland-Niles went down under a challenge from Victor Moses, prompting Atkinson to have another look, but the referee returned to his original decision, awarding a goal kick to Chelsea.
The most contentious decision came minutes from the end as Danny Welbeck left a leg in on Cesc Fabregas inside the box, and though play went on for another minute, Atkinson returned to the call. Replays showed Welbeck got a slight touch on the ball, and Atkinson again returned to his original call of no penalty.
Atkinson did not have to go to the pitch-side screen at any point during the game, and took instructions from VAR Neil Swarbrick in Heathrow.
However, there was some debate around the system's success from both sets of managers. Arsene Wenger was slightly confused about Atkinson returning to the Welbeck penalty incident, and suggested play should be stopped instantly if the referee was not sure.
Chelsea head coach Antonio Conte felt more time should have been added on at the end of the game for the VAR incident and also injuries, with only five minutes of stoppage time included.
