Fired up after a month-long break from competition, Queensland Roar has come out swinging as it prepares to make a last-gasp tilt at an A-League finals berth.

In the countdown to Sunday's must-win away clash at Hindmarsh Stadium, Queensland coach Miron Bleiberg stoked his simmering feud with Adelaide United mentor John Kosmina by saying he would give his rival the cold shoulder "win, lose or draw".

And Roar striker Alex Brosque has also taken an outspoken approach, hitting out at persistent rumours that he has already signed with Sydney FC.

The last time Queensland clashed with Adelaide in October, Bleiberg and Kosmina became embroiled in a sideline spat.

A police officer was needed to keep the pair apart after they became involved in a screaming match at Suncorp Stadium following Adelaide's 2-1 win.

Asked what he would say to Kosmina on Sunday, Bleiberg said: "Win, lose or draw I will not say anything to him".

Socceroos squad member Brosque was also fired up over recent reports that "outrageously" linked him to an off-season move to Sydney FC.

"All this speculation is upsetting for both myself and everyone connected with Queensland Roar," he said.

"I have said it before and I will say it again, I have not made a decision yet and I will wait until the end of the season before doing so.

"I can't change people's minds if they think it is a done deal with Sydney FC but I am on record as saying that my focus at the moment is doing my best for Queensland Roar.

"I still have a job to do here and that is what I am putting all my energy into right now."

Brosque admitted it was "inevitable" that rumours about his future would begin after signing a one-year contract with Queensland this season.

"I hope that I can finally put the record straight by saying once again that I will not make a decision on my future until the end of the season," he said.

Bleiberg will be hoping Brosque can add to his modest season scoring total of three goals as second-last Queensland attempts to stay in the top four finals race against ladder leader Adelaide.

The game will be Queensland's first since a 1-1 draw with cellar dwellers New Zealand on December 1.

Queensland has just six regular season games left but must break its scoring drought after netting just 14 goals in 15 games.

If Brosque doesn't fire, Bleiberg hopes new Brazilian recruit Reinaldo Elias da Costa will after being included in the Adelaide-bound Roar squad.

Reinaldo, 21, was included after bagging three goals in a recent intra-squad game.

Bleiberg said he was still undecided whether to start the striker, who has enjoyed stints at Dutch heavyweights Feyenoord and leading Brazilian side Corinthians.

"He is confident and will definitely figure in the game," he said.

Bleiberg said he was surprised at how well Reinaldo had acclimitised since arriving in Australia barely 10 days ago.

Roar travels to South Australia on Saturday.
