UEFA says it will begin using video review in the Champions League next season, after a debut in the Super Cup.
The UEFA executive committee also decided to approve video assistant referees for the 2020 European Championship and the 2020-21 Europa League.
The first UEFA game using technological help for referees is expected to be Aug. 14 in the Super Cup between this season's Champions League and Europa League winners in Istanbul.
Video review is used for four potentially game-changing incidents: awarding goals, penalty kicks, red cards and cases of mistaken identity.
