LIVE STREAMS How to watch the Champions League in the UK this season
UEFA stipulates that every single stadium in the Champions League has to provide a VAR room for the officials in charge of the system. The main VAR official has to be from the same country as the on-pitch referee - if the league of that nation utilises the technology domestically.
Incident off the pitch or in the tunnel can also be watched by VAR - and VAR can award added time in matches.
