As others have said, while VAR was supposed to end the most obviously poor decisions, we didn't take into account it was the same people currently making those mistakes that would be running VAR.
I don't envy referees, they have a tough job and are surrounded by players who are experts at conning them, plus managers and fans who give them heaps of abuse, sometimes fairly, often not. But the officials running VAR need to start being separate from the other officials. They don't have to be trained referees, they need to have a thorough understanding of the rules and some common sense. Stop the VAR officials from making decisions that sometimes seem to be all about not embarrassing their on-field colleagues.
