In 2017, after a long period of research and testing, video assistant referee (VAR) technology was officially introduced into world professional football. In March 2018, the International Football Association Board (IFAB) permanently incorporated VAR into the Laws of the Game.
Since then, VAR has developed rapidly, with modern, high-quality technology. There are also ways to apply VAR flexibly, depending on the conditions and reality of each country and tournament. From the 2022 World Cup, semi-automatic offside detection technology - considered the most detailed and sophisticated, has been applied.
However, no matter how advanced and detailed it is, VAR - which was born to resolve controversial situations, still leaves controversy. Even the new semi-automatic offside technology recently caused controversy in the match between Barcelona and Real Sociedad. When everyone sees that, even with VAR, football is still football, not without controversy. Therefore, VAR is also considered to make football lose its emotion...
However, the football world has gradually gotten used to life with VAR, accepting it as part of the game. Tournaments have invested to improve the quality of VAR and the referee team... However, while the world is getting used to and adapting, FIFA is planning to replace VAR with another method. It is also technology, but much simpler. It even gives the initiative to the coaches of the teams instead of it being up to the referees (from the field to the VAR room).
That is FVS (Football Video Support). Accordingly, teams will have the right to "challenge" any referee decision that they feel is incorrect - 2 times/match, but if the first time is not successful, they will lose the second right.
FIFA has tested it at the U20 and U17 Women's World Cups, with initial reports saying there were "no problems". It is possible that matches will no longer be broken up as with VAR, but it is impossible to say anything in advance, because football is fundamentally not a repetition. So controversy is still lurking...
In the meantime, FVS has appeared and is preparing to change the VAR equipment. The race for technology continues to make football countries like Vietnam face difficulties.
