Video assistant referee (VAR) technology will be used in the Champions League from next season, Uefa has announced.
The European governing body revealed VAR would be used in the 2019-20 competition from the play-off stage onward, as well as at the 2019 Uefa Super Cup, the Euro 2020 finals, the Europa League group stage from the 2020-21 season and the 2021 Nations League finals.
The decision was made by the Uefa executive committee at a meeting in Nyon, Switzerland on Thursday morning.
Uefa president Aleksander Ceferin said: "We are confident that introducing video assistant referees in August 2019 will give us enough time to put in place a robust system and to train match officials to ensure an efficient and successful implementation of VAR in the Uefa Champions League, the world's flagship club competition."
