The fact that it depends what ground you are playing at in the FA Cup, which determines whether or not it's used is a joke. Either you are able to roll it out for all fixtures, or none.
And the Lacazette thing - with VAR now in place, is there still the retrospective action, if a ref didn't see something? I didn't see the game and none of the highlights I can find show the incident. But surely if no action was taken during the match, then an independent panel should be able to punish retrospectively if they spot an error, as was the case previously.
Or is it now the case, where if VAR looks at something and decides it's not worthy of changing the decision, then there is no retrospective action taken?
