What is VAR, how does it work and what are the biggest problems?
The use of technology in football has been on the increase over the past few years but none seems to create as much heated debate and questioning as that of the Video Assistant Referee (VAR).
By and large, it is felt that minor and visible calls are improved across the course of the season with on-pitch referees getting extra help. However, there have been several high-profile incidents of late that have led to clubs, or personnel within them, complaining about the eventual decision or decision-making process, with the most recent coming in the Champions League.
Manchester United boss Erik ten Hag felt aggrieved that a number of calls went against them infor serious foul play.
