FIFA 'extremely satisfied' with World Cup officiating
FIFA is "extremely satisfied with the level of refereeing" at the World Cup, and hails the introduction of video review as a success.
The new technology system for helping referees make decisions has "on the whole ... been positively accepted and appreciated within our football community," FIFA says.
The introduction of the video review has coincided with more penalty kicks being awarded.
However, Brazil complained to FIFA about Switzerland's goal in a 1-1 draw being allowed to stand, and wanted audio recordings of communication between the match officials to be released.
England fans were bemused as to why rugby-style tackles by Tunisia defenders on forward Harry Kane at set pieces did not earn a penalty. The same video review official in that game was the referee who in an earlier game awarded a penalty to Croatia for a similar challenge by a Nigeria defender.
FIFA concedes there will "still be discussion and divided opinion" about some incidents.
