Melbourne Victory coach Tony Popovic was left frustrated with the referee's decision to award the Newcastle Jets a match-winning penalty on Saturday night.
Victory are priced at 9/2 to win the A-League minor premiership this season but they are having a wobble after suffering back-to-back defeats since last week's FFA Cup Final win over Central Coast.
Victory were on their way to all three points when Jake Brimmer put them in front on the stroke of half-time but a strike by Jets star Valentino Yuel in the 57th minute levelled matters.
The controversial penalty award came in the 70th minute when Newcastle's Olivier Boumal went to ground following a collision with Brendan Hamill.
The referee pointed to the spot and Beka Mikeltadze stepped up to fire home what would turn out to be the winning goal, much to the frustration of Popovic.
"Just no. It clearly wasn't a penalty," he told reporters after the game. "If we're going to start giving penalties for challenges like that then we've really got some issues. That's not a penalty. In my view, that's not a penalty."
Victory also had to play most of the second half with 10 men after captain Josh Brillante was sent off after picking up his second yellow card of the game.
But again Popovic was far from happy with what he felt was inconsistent officiating throughout the game.
"There was a challenge in the first half from Mikeltadze that (should have been) a second yellow," he added. "But he (already) had a yellow so it didn't get a yellow card.
"Josh went (in), it was a challenge, (and) the yellow card came out quickly. If we're going to give yellow cards like that, let's do it all the time. Let's do it throughout the whole game."
