Standard Sport has details from the international governing body of football, FIFA, to demystify how VAR works in different countries.

The purpose of the VAR is to assist the centre referee determine whether there was a violation, that means a goal should not be awarded.
VAR also ensures no incorrect decisions are made in conjunction with the award/non-awarding of a penalty kick. This is in regard to handballs and fouls inside the 18-yard box.
Direct red card incidents
The role of the VAR is to ensure that no wrong decisions are made in conjunction with sending off or not sending off a player.
If the referee books or sends off the wrong player, or is unsure which player should be cautioned, VAR will inform the referee so that the correct player can be disciplined.
How does VAR work?
The referee informs the VAR, or vice-versa - VAR recommends to the referee that a decision/incident should be reviewed.
Review and advice by the VAR
The video footage is reviewed by the VAR, who then advises the referee via headset what the video shows.
Decision or action is taken
The referee decides to examine the video footage on the side of the field before making a decision, or the referee accepts the information from the VAR and takes the appropriate action.
Background of VAR
The Australian League (A-League) became the first to VAR system in a top flight professional club competition on April 7, 2017.
The first VAR intervention in a professional league game was witnessed the next day, April 8, when Wellington Phoenix played Sydney FC. VAR identified an unlawful handball in the penalty area and gave Sydney FC a penalty. The game ended in a 1–1 draw.
2018 FIFA World Cup
FIFA formally approved the use of VAR for the 2018 FIFA World Cup during the FIFA Council meeting on March 16, 2018.
The mouth-watering tournament became the first competition to use VAR in full.
Top European Leagues
The VAR system was introduced in top flight European football by the German Bundesliga and the Italian Serie A at the beginning of the 2017-18 season.
The technology was introduced in Spanish La Liga at the beginning of the 2018-19 season.
On 15 November 2018, English Premier League teams voted in principle to bring Video Assistant Referees to the Premier League from the 2019–20 season.
On 12 November 2019, chairmen of many Premier League clubs demanded that the Video Assistant Referee system either be improved or completely scrapped in light of many controversial decisions seen in matches.
Since the introduction of VAR at the start of the 2019-20 season, the use of the technology has been harshly criticised by fans, clubs, managers and even some players.
The Premier League was the last of Europe’s top leagues to introduce the use of video technology to help out officials, but the inconsistency and decision-making has continued to anger fans.
Like it or not, football fans are going to have to live with the reality that Video Assistant Referee (VAR) is here to stay.
