The experiment with VAR has pleased FIFA at the Confederations Cup but there is no commitment yet to use it at the 2018 World Cup in Russia.
FIFA's head of refereeing Massimo Busacca praised the implementation of video assistant referees (VAR) at the Confederations Cup but conceded the much-discussed system must be reformed and improved.
The use of VAR has come under the spotlight on a number of occasions during the tournament in Russia, most recently during Germany's 3-1 win over Cameroon in Sochi on Sunday when referee Wilmar Roldan sent off the wrong player before having his mistake corrected.
