Thibaut Courtois said he is a fan of using technology to help out officials ahead of Real Madrid's first Champions League fixture with the involvement of VAR.
UEFA will have a VAR team - consisting of a video assistant referee, an assistant video referee and two video operators - in action for all knockout games in the remainder of this season's competition.
LaLiga introduced the use of video replays for the 2018-19 campaign, so Madrid have experience of playing under such circumstances. It was also used at the 2018 World Cup, where Courtois helped Belgium reach the semi-finals.
