Western United boss John Aloisi hit out at the match officials for missing what he thought was a clear penalty in the 1-0 defeat against Melbourne Victory.
Western are gunning to win the grand final but they have work to do to overturn the semi-final first-leg defeat and book their place in the big dance.
Jake Brimmer grabbed the only goal of the game in the 74th minute with a stunning volley but Aloisi feels his side should have been given the chance to take the lead well before then.
The Western boss felt they should have had a penalty after just five minutes when Victory defender Jason Davidson went into the back of Lachie Wales. But unfortunately for Western it was not awarded.
"We all saw it. The referee obviously didn't see it. The assistant referee didn't see it, I don't know how. But the VAR missing it has happened to us all season so I expected the VAR to miss it," Aloisi said.
"Anyone that understands the game will know that's a clear penalty. There's no intent to play the ball. He's pushed him from behind. That's disappointing because when it's so clear, you expect if the referee doesn't see it, then help him."
Despite the defeat, Aloisi was pleased with the performance of his side and says his side are still in with a good shout of making the grand final.
"We limited them to a few chances, if any, and they had to score a special goal to win the game," Aloisi added. "To be honest, we're well and truly in this tie. This is the first half, we're 1-0 down."
