Nyon: UEFA has taken a massive step towards cementing video technology, creating the 'Clear Line' platform, a guide which can be used by anyone to know how and when a video assistant referee should intervene. "We drew on our experience spanning around 8 years, on the various VAR cases, and on more than 100 clear clips, and we created Clear Line. It is a document in which we explain when and how the video assistant referee should intervene, and it has been prepared so that everyone can have a clear line. Another UEFA official, Velasco Carballo, said that "it is not a web page for referees or referee organisations". "This is a web page created to explain our basic principles to anyone.
