Elvis Kamsoba’s 32nd-minute red card cost Melbourne Victory a 3-0 defeat to their rivals, Sydney FC, on Sunday.
Victory were down a man when Elvis Kamsoba received a second yellow card. Kamsoba’s first yellow card came in the 14th minute when he miss-kicked the ball in midair as the fourth official Jonathan Barreiro had intervened to let referee Daniel Elder know the incident deserved a yellow card.
"I've got no problem with the fourth official intervening to suggest there's a yellow card but at what point do we draw the line?" Brebner said.
"Is that every tackle, every one that's missed - the fourth official will just step up now and give his opinion - 'that's a yellow card'?
"I'd understand if it was a straight red but to stop the game and tell the referee it should have been a yellow? Then it needs to happen at every opportunity and every time.
"Because I do remember a few weeks ago when Marco Rojas breaks his nose ... something that was a lot worse than Elvis' tonight, I didn't see the fourth official saying 'actually, it could have been a red, that one'."
Brebner vowed to fight out the season despite being at bottom of the A-League’s table, he continued: "One thing we won't do is throw in the towel. We'll endeavour to get as many points as we can over the remaining games.”
Goals from Bobo, Kosta Barbarouses, and Alexander Baumjohann gave the reigning champions all three points as Sydney’s coach, Steve Corica, couldn’t be happier with his side’s performance.
"We should have had a few more tonight but it was a very dominant performance," Corica said.
"Obviously with 10 men for them it makes it harder for them, but you still have to get the goals and produce the goods and I think we did that."
