The Evolution of Football: How VAR is Changing the Game

Football, the beautiful game, has seen many advancements over the years. From tactical innovations to technological breakthroughs, the sport continues to evolve. One such technological advancement that has made a significant impact on the game is Video Assistant Referee (VAR). In this article, we will explore the ins and outs of VAR and how it is shaping the future of football.

What is VAR and How Does It Work?

VAR, which stands for Video Assistant Referee, is a tool used in football to assist referees in making more accurate decisions on critical game-changing situations. It is a system operated by a team of officials who monitor matches remotely on multiple screens and have real-time access to video footage from various camera angles.

VAR can intervene in four specific situations: clear and obvious errors, serious missed incidents, goals and incidents in the penalty area, and mistaken identity. In these scenarios, the on-field referee can request a VAR review or the VAR team can alert the referee if they believe a clear error has been made. The final decision, however, always rests with the on-field referee.

The History and Implementation of VAR

The concept of VAR was first introduced as part of the “Referee 2.0” project by the Royal Dutch Football Association (KNVB) in 2010. However, it took several years for the system to be implemented and accepted globally. After successful trials and experiments, VAR was first officially used in a professional match in September 2016, during a friendly between Italy and France.

Since then, VAR has been gradually adopted by various leagues and competitions worldwide. It made its mark on the international stage at the FIFA World Cup 2018 and has since been implemented in over 100 tournaments across the globe.

VAR’s Impact on the Game

The introduction of VAR has had a profound impact on the careers of players, coaches, and teams. Before VAR, referees’ decisions were final, and players and fans had to accept them, even if they disagreed. However, with VAR, questionable decisions can be reviewed and corrected, providing a fairer and more transparent environment for the game.

Let’s take a look at some notable instances where VAR could have changed the course of football history:

1. Jose Mourinho’s Career Path

Jose Mourinho’s rise to fame as a manager began with a Champions League match between his Porto side and Manchester United. A controversial decision by the assistant referee had a significant impact on the outcome of the game, favoring Porto. If VAR had been in place, the decision could have been reviewed, potentially changing the outcome of the match and altering Mourinho’s career trajectory.

2. USMNT’s World Cup Journey

During the 2002 World Cup, the United States Men’s National Team (USMNT) reached the quarter-finals for the first time in history. In their match against Germany, a handball by a German player inside the penalty area went unnoticed by the referee. If VAR had been available, the decision would have been reviewed, possibly resulting in a penalty for the USMNT and changing the outcome of the match.

3. Manchester United vs Wigan

In a Premier League match between Manchester United and Wigan, a handball inside the penalty area by a Wigan player was not awarded as a penalty. If VAR had been in use, the correct decision could have been made, potentially affecting the result of the match and the outcome of the Premier League title race.

4. Arsenal’s “Invincibles” Run

During Arsenal’s unbeaten Premier League campaign in the 2003-2004 season, there were instances where VAR could have changed the course of history. In one particular match against Portsmouth, a controversial penalty was awarded to Arsenal, which could have been overturned if VAR had been in place. This decision affected the result of the match, potentially altering the team’s unbeaten record.

5. Chelsea’s Champions League Exit

In a memorable Champions League semi-final match between Chelsea and Barcelona, controversial decisions by the referee favored Barcelona, leading to Chelsea’s elimination from the competition. The absence of VAR allowed questionable calls to stand, which had a significant impact on the outcome of the tie.

6. Overcoming the “Fifth Game” Curse

The Mexican national team has historically struggled to advance to the fifth game (quarter-finals) of the World Cup. In past tournaments, controversial goals have been allowed due to incorrect offside calls. With VAR in place, those questionable goals could have been disallowed, potentially breaking the curse and allowing Mexico to progress further in the tournament.

7. The Greatest Goal Controversy

There have been numerous instances where goals have been awarded or disallowed due to incorrect decisions by referees. With VAR, these controversies could have been resolved, ensuring fair play and accurate results.


In conclusion, VAR is a valuable tool that is improving fairness and accuracy in football. It has the potential to change the outcome of matches, impact the careers of players and coaches, and shape the development of the game. With the examples discussed, it becomes evident that VAR plays a crucial role in creating a fair and transparent playing environment.

As VAR continues to be implemented in more leagues and competitions globally, we can expect further advances in the technology and its integration into the fabric of football. The future of the game looks promising, with VAR leading the way towards a more just and accurate implementation of the rules.
