Macarthur FC manager Dwight Yorke has called for better judgement from VAR after two controversial calls in the 3-2 loss to Sydney FC cost his side.
Sydney FC's first goal on Saturday night came directly after Bulls defender Matthew Millar was ruled to have fouled Robert Mak in the box at Campbelltown Stadium.
Replays showed it had been Millar who fell to the ground first as he competed for the ball but the VAR upheld the decision to award Sydney a penalty.
While Mak's strike was blocked, Patrick Wood poked the ball into the net on the rebound.
The VAR became involved again later in the half, awarding a game-changing red card to Bulls defender Jonathan Aspropotamitis.
Aspropotamitis was originally shown a yellow for impeding Wood as the pair jostled for the ball 10 metres outside the box with only Bulls goalkeeper Filip Kurto in front of them.
The VAR chose to upgrade the punishment to a red, leaving Macarthur a man down for the remainder of the game and fighting a losing battle to stay in the contest.
Yorke said he struggled to understand how the VAR had complicated, rather than simplified, the decision-making process.
"How can you actually visually see those incidents and come up with the wrong decision?" Yorke asked.
"The inconsistency of the VAR, the VAR actually highlights all these things and yet the decision-makers are getting it wrong. I just can't get my head around it.
"In my opinion, when you look at those decisions, they are very tight, very close.
"You've got to be 100 per cent right in making those decisions. If you're not, we pay the consequences."
While Yorke was frustrated to have dropped his first game as manager of the Bulls, he said he would not ask the A-Leagues to explain the rationale behind the two refereeing calls.
"It's not going to change the results now," Yorke said.
"I'm just hoping we're not going to be in this position (again). We're asking for consistency.
"Certainly the penalty (against Millar) is definitely not a penalty and that was the game-changer right there."
For the second time in as many weeks, Sydney FC were on the right end of a controversial red card.
While coach Steve Corica admitted last week's decision to dismiss Adelaide United striker Hiroshi Ibusuki was "harsh", he threw his support behind the match officials after the Macarthur win.
"I think the referee got it right," Corica said.
"He looked at both of them, the VAR checked it and for me, they're the right decisions."
Corica was especially confident that Aspropotamitis deserved to have been red-carded.
"He was the last man," Corica said.
"'Woody' was going in on goal and no-one would have caught him. I think (the red card) is the right decision."
