Video assistant referee (VAR) technology will be used in the Champions League for the 2019-20 season, UEFA has announced.
The technology will also be used 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 Champions League, the world's flagship club competition."
