VAR has been tested in the UK, Germany, Italy … but only really attracted attention when officially applied in the World Cup 2018.
VAR stands for Video Assistant Referee. The camera system will be installed around the yard or on the stands to record the situations in the match.
When the ball is still rolling on the field, the assistants sitting away from the stadium will watch videos that slow down the situations just happened. Through wireless headsets, they communicate with the referee, giving their advice about any incidents that can change a match. As a rule, VAR only supports arbitration in four areas: a goal is scored, there is a chance of a foul, a red card and a case of misidentification of the player.
VAR is essentially a technology that helps referees make decisions, but cannot completely replace grassy kings. The final decision is still made by the referee. This technology avoids unnecessary controversy, such as a goal not recognized in the match against England in the 2010 World Cup. When a team complains about a certain situation, or the referee feels uncertain. When making a decision, VAR will also be used to detect offside, shirt pull, collision …
The penalty is the area which VAR is most used because it helps the referee give correct penalty decision. According to SkySports statistics, with VAR’s presence, the Russia-held tournament is the World Cup season has a record of penalties as well as the highest scoring rate from fixed situations. Specifically, a total of 22 penalties were taken in 64 matches, while the previous record was only 18 in 1990, 1998 and 2002.
Although it was first applied at last year’s World Cup, VAR has often become the key technology. In the match between Portugal and Spain, Diego Costa’s goal became the first in World Cup history to be recognized under the help of VAR.
