Other than offsides (which a computer decides) VAR isn't solving anything when a ref/official makes the decision, as with the penalty we didn't get against Spurs, and the penalty we didn't get today, the decision makers are either incompetent or biased. On both occasions, numerous people including former officials and players, media, pundits and fans of all teams thought they should have been penalties.
The only decisions we can trust are offsides and goal line technology, because there is no one making the decision, the technology does it.
