European football’s governing body had previously stated its intention to introduce VAR only from the start of the 2019/2020 season.
“If we can do it before, why wait? We cannot afford any mistakes if we can do it earlier,” said UEFA president Aleksander Ceferin after a meeting of the European football body’s Executive Committee.
VAR is already used in a number of Europe’s top leagues, including Spain’s La Liga, Germany’s Bundesliga and Serie A in Italy and was widely seen as a success at this summer’s World Cup.
The Europa League final and the under-21 European Championships in Italy in June will also use VAR.
