Western United coach Mark Rudan wants VAR officials to make public explanations of their decisions on potential penalty incidents in games.
Rudan claims his club is the only one in the A-League yet to get a favourable call from the controversial system.
And he said based on new interpretations of handball explained by referees to his club in the pre-season, United should have been awarded two penalties in the second half on Sunday, when they lost 1-0 to Central Coast in Gosford.
He wanted more clarification regarding VAR decisions.
Rudan was both passionate and measured in his argument, but joked he wasn't going to get as fired up as Western Sydney counterpart Markus Babbel, who let rip with a couple of F-bombs after his team had a contentious penalty awarded against therm two nights earlier.
''I'm not going to answer like my colleague on Friday night did, but I'm right behind him and I'm right behind all the other coaches that have been on the wrong side, I'd love a please explain," Rudan said.
"It's important that if us coaches and players are out in the public, making comments like this and sitting here, it's important the people who sit out in that VAR room come out.
"I would love some clarification on what is and what isn't and I think the people who are making these decisions, who are hiding in a box somewhere in the country, need to come out and publicly explain each incident.
"The coaches, the players and the fans can understand exactly what warrants a penalty and what doesn't."
His Mariners counterpart Alen Stajcic doubted whether there could be any more clarity regarding natural and unnatural handball actions.
"Handball has changed 50 times in the last 20 years and every time you change it it just moves the grey area so it doesn't solve any problem," Stajcic said.
"We've already been stung by a couple of handballs in the box, in round one and round two, so we've probably been at the brunt of more of those decisions more than anyone else, so it is what it is."
Rudan was clearly frustrated by the VAR calls in matches involving his club throughout their first season.
"Not one VAR decision has gone our way this year, not one," Rudan said.
"Every team has had it go their way this year except for us."
