Fans at Sunday's Carabao Cup final will be told if the video assistant referee (VAR) is reviewing a decision by a graphic on Wembley's electronic screens, the English Football League has confirmed.
The simple message will say 'VAR Review', and would have been used during the competition's semi-finals but there were no long reviews in those games.
The match between Arsenal and Manchester City will be English football's biggest game yet to use video review, and one of the main criticisms so far has been that supporters at matches are not aware of what is happening when play stops for a review.
