FIFA president Gianni Infantino insists VAR is here to stay despite criticism in the Premier League.
However, leagues and competitions do not have to use the technology if they wish not to.
VAR was installed permanently across European leagues at the start of the season, amid major anticipation from fans.
But teething problems in England especially has brought major criticism when it comes to how the technology is being used.
There has been talk of major changes being made to help combat the problems – but while Infantino admits VAR isn’t perfect, he insists it is here to stay.
“VAR is now indispensable,” said the former UEFA secretary general.
“If used how it should be, the criticism will subside. It can be perfected, but the fact is that in some countries they don’t comply fully with the IFAB protocol.
“It’s important to understand that VAR helps the referee, and not that it’s someone else who makes the decisions.
“Meanwhile, it is used in a hundred tournaments in seventy countries.
“We will have to invest more, according to my vision from 2020 to 2023, to have a VAR that’s light, economical and functional. Global.
“Let’s clarify once and for all: there’s no obligation. Those who don’t want it, are free not to use it.
“But ask the critics if they would really want to go back to the Stone Age.”
It’s unclear when football fans will once again be able to critique the game’s new technology as the coronavirus outbreak continues to wreak havoc with everyday life.
And Infantino also admits he is in the dark over fixtures restarting.
Health comes first, then everything else,” he added.
“For the managers, the rest means hoping for the best but also preparing for the worst.
“Without panicking, let’s stay it clearly: we will play again when we can do it without putting anyone’s health at risk.
“Federations and Leagues are ready to follow the recommendations of the governments and WHO.
“I thank the doctors, nurses and all those who risk their lives to save others. They are heroes.”
