Goal-line technology seems to be going well. VAR, on the other hand, has been a divisive topic. We've had "experiments" in the Club World Cup, the U-20 World Cup, and now the Confederations Cup. It's correctly overturned some decisions, but it's been controversial with others, and problematic elsewhere. There are three major concerns from my experience: 1) It absolutely RUINS goal celebrations. In a sport that usually has low scores, immediate and uninterrupted goal celebrations are crucial for the entertainment value. 2) It is not always clear what specific decision the VAR is being used for. There needs to be clear rules on what VAR can be used for, what it is being used for, and what the outcome of the review is. All the confusion we've seen is because no clear explanation was given in real time about the review, or the interpretation of VAR that leads to the upholding/reversal of a decision. 3) It is still subjective. Hawkeye for ball-tracking uses an objective technology, and goalline decisions benefit for it. VAR is a referral system, and still involves the human element. I'm personally OK with that, so long as point #2 is addressed. How does everyone else feel about this? Are there other concerns with VAR that need to be addressed?
