VAR has proven a considerable talking point so far in what is its debut season in the English top-flight, and not least over the last few days, during which a number of decisions have been under the spotlight.

"Let's be real - we are dealing with human beings and human beings will always make mistakes," Hackett said.

"VAR is there for us to see a game with less errors and hopefully move the decision-making process, accuracy, into the high 90 per cents. We are not achieving that, anywhere near."

Hackett, who agrees with the view that there is a reluctance among VAR officials to overrule 'subjective' decisions, wants to see more use of the pitchside monitor so that on-field referees are reviewing their own calls.

"I come from a point of being very positive about the use of technology to aid refereeing decisions. I have supported VAR and I'll continue to support VAR," he said.

"However, I think .... we need to review how the system is operating and ask why are we doing it different to other countries, and to how it operated in the World Cup.

"Why have they decided not to use the pitchside monitor? It's been used in other competitions around the world and it's part of the criteria of the International Football Association Board.

"Let us get the officials together and let us understand we are going to use the pitchside monitor. Let everybody be aware that it's going to delay the process, but the outcome has to be a more accurate decision than we are getting at the moment."
