Video Assistant Referee (VAR) is a football assistant referee who surveys choices made by the head official with the utilization of video film and a headset for correspondence. In 2018, VARs were composed into the Laws of the Game by the International Football Association Board (IFAB) following preliminaries in various real rivalries.
There are 4 types of decision that can be reviewed by VAR.
Goals – The job of the VAR is to help the arbitrator to decide if there was an encroachment that implies an objective ought not be granted. As the ball has gone too far, play is hindered so there is no immediate effect on the diversion.
Penalty decisions – The job of the VAR is to guarantee that no unmistakably wrong choices are made related to the honor or non-grant of an extra shot.
Direct red card decisions – The job of the VAR is to guarantee that no plainly wrong choices are made related to sending off or not sending off a player.
Mistaken identity – The official alerts or sends off the wrong player. The VAR will illuminate the ref with the goal that the right player can be restrained.
How does video assistant referee (VAR) work?
Incident occurs – The ref illuminates the VAR, or the VAR prescribes to the arbitrator that a choice/occurrence ought to be investigated.
Review and advice by the VAR – The video film is looked into by the VAR, who exhorts the arbitrator through headset what the video appears.
Decision or action is taken – The official chooses to survey the video film in favor of the field of play before making the fitting move/choice, or the arbitrator acknowledges the data from the VAR and makes the suitable move/choice.
The procedure starts with the video aide ref and the associate video colleague arbitrator (AVAR) looking into the play being referred to on a bank of screens in the video task room (VOR) with the help of the replay administrator. This can be activated by the arbitrator mentioning the audit or by the VAR directing a “check” to check whether a survey ought to be prescribed to the ref. In the event that the VAR discovers nothing amid the check, at that point correspondence with the arbitrator is superfluous, which is known as a “quiet check”. On the off chance that the VAR accepts there has been a potential clear blunder, the ref will be reached with that judgment.
The official flag for a video audit is the arbitrator making the layout of a square shape with his forefingers (showing a video screen). This goes before both any OFR just as any adjustment in the first call. Players who request a video survey by making the square shape movement too much are to be advised with a yellow card. Players who enter the zone where the arbitrator leads an OFR are likewise to be forewarned with a yellow card, and group authorities who do as such are to be rejected.
The associate video right hand arbitrator (AVAR) is a present or previous official delegated to help the VAR in the video activity room. The obligations of the AVAR incorporate watching the no frills on the field while the VAR is attempted a “check” or a “survey”, to keep notes of occurrences, and to convey the result of an audit to supporters.
