video assistant referee (VAR) -> assistente video dell’arbitro
The video assistant referee (VAR) is an association football assistant referee that reviews decisions made by the head referee with the use of video footage and a headset for communication. VARs are not currently part of the Laws of the Game, but their use is currently being trialled by the International Football Association Board in a number of different competitions.https://en.wikipedia.org/wiki/Video_assistant_referee
