I agree. Even as a Barca fan and even as I said previously, that the tiny small margins should always be given benefit of doubt to the attacker. It is a tough call to make, but especially if there is doubt, and 50/50, you should actually award the on field referee decision first of all. Remember, all these things are assistants, referee is always the first call, IMO.
But enough about it, lets get on with it. We don't need VAR to cloud our game. Hope Flick keeps his head on and not lose it like Xavi. The goal wouldn't have guaranteed we won or even got 1 point anyway.
