Mourinho questioned whether the decision was down to ignorance or deliberate choice. He insisted that incompetent officials should not be operating the technology during matches.
"We lost to Betis because we failed to convert our attacking play into goals," Mourinho said, as quoted by Mundo Deportivo. "But regarding the penalty, why wasn't it retaken? Was it because VAR didn't know the rules, or because they chose not to? Why? If VAR didn't order a retake because they didn't know the regulations, they should go home; if they chose not to, that’s even worse. And why didn't VAR call the referee over? It’s strange.
"I want to give them the benefit of the doubt and assume they didn't know the rules, but if that's the case, they shouldn't be in the VAR room. They should go home. Because what will happen is that, in the coming months, if the exact same situation arises, the penalty will be retaken. I want to make it clear that we didn't lose because of that - we might well have missed the retake - but as a football coach, I want to know why it wasn't retaken."
