Arsenal will try to cure some of the confusion around Video Assistant Referee (VAR) technology on Wednesday night with fans being notified of reviews for the first time.
The Carabao Cup semi-final second leg against Chelsea will be the first game to feature big-screen graphics in the ground, letting supporters know when VAR is being used.
The EFL have sent Arsenal Carabao-branded graphics to display on their two giant screens suspended from the stadium’s roof in the latest step of technology trials.
The move is aimed at clearing up crowd confusion at the Emirates Stadium, after fans were left baffled when referee Martin Atkinson asked for a video review into Danny Welbeck’s challenge on Cesc Fabregas late in the first leg.
