The scousers penalty today is a great example of why VAR as it operates isn’t and cannot be a tool to help refs make better decisions in a quick sport (what it was sold as)
The offence is a possible foul involving contact. So under IFAB rules it is a direct free kick offence which attracts a penalty where the player is careless, reckless or uses excessive force in the contact.
The credible view of the incident is that the Liverpool player went past the United one, began to fall, then initiated contact with the united players leg by kicking it when they could have avoided it but in any event whilst already falling to the floor. You can see this clearly in the slo mo. It doesn’t meet the IFAB definition of the offence
A properly functioning VAR system would post incident have the ref view the screen. Whilst the footage is being cued up the ref would be reminded of the terms of the law of the game. They would then view the footage and decide whether it fell foul of the law or not and explaining their reasons
At present someone in a room somewhere makes a further subjective call on a refs subjective call and no one hears any of the reasoning and we get a decision. It really good get much better if the powers that be went back to first principles. All you need is a ref and tech available to him to make better decisions. The VAR room don’t need to be refs. They just need to remind the ref of the relevant law, cue up the video for him to review, ask him to describe the r incident and say what he says, and then ask him to apply that to the law and make the decision. All public transparent and fact and rules based with the ref in charge
