Western United coach John Aloisi was left confused after referee Shaun Evans awarded his side a late penalty against Sydney FC, only to change his mind and deny them the chance to win the game.
Western are priced at 11/2 to win the A-League minor premiership and still remain at the top of the ladder despite their failure to pick up all three points.
The game was on a knife edge at 1-1 after Sydney's Max Burgess had cancelled out Steven Lustica's opener, but there was still time for some controversy in the dying moments.
Western thought they had a penalty when Evans adjudged that Rhyan Grant had handled a Dylan Wenzel-Halls header in the area and pointed to the spot.
But then after reviewing the replay at pitchside he changed his mind, much to the frustration of the Western players and bench.
"I'm not totally sure of where the handball is? Is it the sleeve now is not handball or is it below the sleeve? If it is the sleeve well then I'm going to get my players to wear a longer sleeve," Aloisi said after the game.
"I'm not sure if it's clear and obvious to overturn it. Disappointed, yes, but we have to get on with it and sometimes these decisions will go for you and sometimes against you. Unfortunately it went against us."
It comes as no surprise that Sydney FC boss Steve Corica thought the referee was right to overturn his initial decision.
"There's no way Rhyan Grant could've got his hand down from there, he jumped for the ball and he's on his way down and they headed it straight into his hand," Corica added. "I was a bit worried but obviously they made the right decision."
