Fifth and sixth official are already used in matches in the Europa League and the UEFA Champions’ League. The system was also used during last summer’s Euro 2012 tournament in Poland and the Ukraine.

Belgium will be the first European country to use the system in national competitions. The well-known former referee Pierluigi Collina and the Belgian Football Association will explain more at a press conference to be held on Tuesday week.
