Costa Rica head coach Oscar Ramirez said Thursday that the video assistant referee (VAR) system, used at the 2018 FIFA World Cup in Russia, slows down the game.
The tournament in Russia is the first World Cup where VAR is used to help match officials avoid possible mistakes by reviewing video replays of game episodes.
"There was a moment when a whole minute was needed to understand what happened during the match, what happened in this or that moment. There are good things about VAR, too. The most important for us is to feel the game. VAR slows down the game a little," Ramirez told journalists.
Costa Rica will face Brazil in their second World Cup match in St. Petersburg on Friday.
