The use of video technology at the Confederations Cup was a major talking point and promises to remain so over the coming months
After years of calls for video technology to be implemented into football in order to help referees, we saw its first major rollout at this year's Confederations Cup.
Far from eliminating debate around refereeing decisions, however, the new system resulted in more discussion and controversy over officiating than would be expected as normal.
Overall, there has been good and bad moments for VAR - as it has come to be known - and it is sure to continue to be a talking point during the coming months.
