The Brazilian Football Confederation (CBF) has asked world football’s governing body, FIFA, for the procedures used for video review during the 1-1 draw with Switzerland on Sunday night.

The Switzerland clash was the five-time world champions’ World Cup Group F opener at the ongoing tournament in Russia.

According to the CBF, FIFA should reveal whether the Video Assistant Referees (VAR) system was used during two key second-half incidents that went against the Brazilians during the game.

The first incident was a push on defender Miranda which led to Steven Zuber’s equaliser for Switzerland, and the second was a penalty appeal waved away after Manchester City Gabriel Jesus went down in the box.

The confederation said via a statement on Monday that: “these two actions constitute … clear errors by the referee, which thus should form part of the reviewable decisions that are analyzed through VAR.” and that it’s important to know whether the incidents were reviewed in any way, saying “transparency is of essence.”

In addition , the statement also requests “video and audio recordings” that might have been employed by the match officials during those incidents.
