Switzerland head coach Vladimir Petkovic said Thursday that the video assistant referee (VAR) system helps to develop football and the quality of referees' decisions has improved after its introduction.
"VAR is a good development for football. We saw that thanks to it, some corrections have been made in several matches. The quality of [referees'] decisions has improved. We should all participate in this process. We are trying to help poorer countries to use this system, we are going in the right direction," Petkovic said.
VAR was used for the first time at Russia's FIFA World Cup during the Group C match between France and Australia, which took place in Kazan on June 16. With the help of VAR, Uruguayan referee Andres Cunha awarded France a penalty in the 55th minute, which was later converted by striker Antoine Griezmann.
The VAR system is used at the World Cup 2018 for the first time ever.
