VAR is due to make its UEFA Champions League debut on Tuesday (February 12) as the knock-out stages of the competition get going.
The video assistant referee (VAR) is due to make its UEFA Champions League debut on Tuesday (February 12) as the knock-out stages of the competition get going.
European soccer's governing body previously opted against using VAR this season, despite the technology being employed by major European leagues in Spain, Italy and Germany, and by FIFA at the World Cup in Russia.
But UEFA, led by Aleksander Ceferin, revised it stance in late 2018 and agreed to roll out the technology in this season's knock-out stages of the Champions League, the Europa League final and this summer's Nations League competition.
The Champions League returns this week with Real Madrid visiting Ajax, Tottenham facing off with Borussia Dortmund, Manchester United playing Paris St. Germain and last season's semi-finalists Roma taking on Porto.
