The president of Russia's Football Union, deputy prime minister Vitaly Mutko, said on Saturday that the country was in talks with FIFA on using the Video Assistant Referee (VAR) technology at some of its stadiums.

VAR, which uses two video officials who monitor the action on screens and call the match referee's attention to mistakes or omissions, is being tested at four Russian stadiums hosting the Confederations Cup, a test event for next year's World Cup.

World governing body FIFA has already said it would like to use video assistant referees at the World Cup in Russia.
