UEFA and European referees are hard at work preparing for the introduction of video assistant referees (VAR) in UEFA competitions from next season. At a four-day course in Madrid, a group of referees with limited experience of VAR in their own countries took part in intensive theoretical and practical sessions, which are enabling them to learn the ropes in time for the launching of VAR in the 2019/20 UEFA Champions League from the play-offs next August. They were joined on the last day by elite referees already experienced with VAR, as UEFA adopts and fine-tunes a unified approach to the system for all of its referees. The course in Madrid was hosted by the Royal Spanish Football Federation (RFEF) at its Ciudad del Fútbol national training centre at Las Rozas, just outside the capital, and followed a first course last month at the Royal Netherlands Football Association (KNVB) national centre in Zeist. The video assistant referee reviews decisions made by the referee in certain key match situations with the use of video footage and a headset for communication. This year, VAR was incorporated into the Laws of the Game by football’s lawmakers, the International Football Association Board (IFAB), following trials in major competitions. The decision to introduce VAR in UEFA competitions was taken by the UEFA Executive Committee in September. In addition to the UEFA Champions League, the committee decided that VAR would also be used at the 2019 UEFA Super Cup. UEFA plans to subsequently extend the deployment of VAR to the final tournament of UEFA EURO 2020, the 2020/21 UEFA Europa League (group stage onwards) and the 2021 UEFA Nations League Finals.
