VAR has become a major talking point in English football over the last year or more after it was first used on these shores for selected FA Cup games last season.
FIFA then made use of the additional technology at the World Cup in Russia. It has since returned to selected FA Cup games in 2018/19, been added to the Champions League by UEFA, and will soon be in use in the Premier League as of next season.
There are myths perpetuated by some pundits, commentators and journalists about how confusing it all is - (it absolutely isn't confusing at all) - and it hasn't been without critics, but the system works when correctly used, and actually works well.
