Fifa has defended its use of video assistant referee (VAR) technology at the Confederations Cup after several confusing incidents, and insisted that the technology remains 'the future of football'.
The VAR system has been used five times in Russia, causing confusion for players and spectators alike.
But Fifa president Gianni Infantino has backed the technology, saying: "We have seen how video assistance has helped referees to make the correct decisions.
"I am extremely happy with VAR so far. This is a milestone tournament."
The system was used in a Fifa competition for the first time in December during the Club World Cup in Japan, and to date is being used in selected competitions.
But many people have complained about VAR after Portugal defender Pepe had a goal disallowed for offside against Mexico, while Chile forward Eduardo Vargas had a strike ruled out against Cameroon thanks to a very tight offside call.
Vargas also benefitted from the system late in the same game when his injury-time strike was ruled OK after being referred to the video assistant referee.

In Monday’s Australia versus Germany clash, Australia’s goal second goal by Tomi Juric was eventually given after review for a suspected handball in the build up.
Fifa said that all five incidents referred to the VAR were goal situations, four related to offside decisions and the other concerning a handball.
"The VAR tests during this Confederations Cup are also helping us to improve the processes and fine-tune communication,” said Infantino.
"What fans have been waiting for so many years is finally happening," he added.
