Vagaries of VAR cause confusion

Introduced to stamp out controversy over refereeing decisions, VAR - the video review system making its World Cup debut - is too often doing the exact opposite.

Debate has raged over numerous incidents in Russia, most notably Stefan Zuber's equalizer for Switzerland in Sunday's 1-1 draw against Brazil, and two strong Harry Kane penalty appeals during England's 2-1 victory over Tunisia.

Brazil has asked FIFA to explain why a push on Miranda by Zuber, just before he headed home, was not even referred for a review.
