Farina took umbrage to referee Chris Beath's decision to send Tommy Oar from the ground after the youngster collected two yellow cards in the space of two minutes.

The former Socceroos coach exchanged words with fourth official Alan Milliner and Milliner registered his disappointment with Beath.

Beath had no hesitation in making Farina follow Oar off for an early finish.

Roar media manager Daniel Lato prevented Farina from speaking his mind at the post-match press conference, saying it simply was not 'prudent'.

Farina's understudy Rado Vidosic took his place and made his thoughts clear on Oar's dismissal.

"There was no malice in that tackle, maybe he was a little bit late, but he should not (have) sent him off for that, that's for sure," Vidosic said.

"There were some heavier tackles unpunished, so I think it was a little bit harsh."

Ricki Herbert was not willing to enter the debate about either Farina or Oar's dismissal.

Roar skipper Craig Moore said there was disenchantment amongst A-League players about how referees were 'not being held accountable for poor performances'.

"I'm not talking about today's game, I'm talking about in general," Moore said.

"There is disappointment ... as players we are judged by our performances, managers are judged by their results, and we're accountable for what we do on and off the field."

"At the moment, it seems to be a little bit different for referees."

Moore believed that ultimately there were far bigger issues to deal with after a 'lacklustre performance' in the second half.

He added: "At the end of the day, that's out of our control, the disappointing side was that we got ourselves ahead and we really didn't finish the job off.

"It's always hard to concede a late goal like that and home form is very important...that's two weeks in a row where we have given away two points."

"We said at halftime we had to come out and be focused, be aggressive and look to play at a decent tempo - and that didn't happen."
