Barcelona president Josep Maria Bartomeu has accused the VAR of favouring the same team as he hinted the system was stacked in favour of La Liga title rivals Real Madrid.
The Blaugrana official made the statement following Barca's 4-1 victory over Villarreal, which saw the Catalans move four points behind Madrid with four games remaining.
Bartomeu referred to watching Madrid's 1-0 victory over Athletic Club in San Mames on Sunday before revealing his dismay at the decisions made by the video technology.
