Var is just like any tech, its very rarely the tech that ats fault it is almost always the users who then blame the tech to mask their ignoranceThis is the problem, the way it has been used and fiddled about with has left many against it.
Yet watch a world cup or Seria A(now with refcams), or AFCON and you see it used effectively, then go to a game here and get deflated by it being implemented poorly.
