A fired-up Ange Postecoglou refused to shed any light on speculation he could walk out on Brisbane Roar as the A-League club strives to complete a massive six days on the pitch.

Brisbane's Asian Championship League (ACL) journey can continue if it beats 2011 K-League runners-up Ulsan Hyundai at Suncorp Stadium tonight.

The Roar then defends its A-League crown against Perth Glory at the same venue on Sunday.

Postecoglou, who's won over Brisbane's sporting public by turning the Roar into a magnificent team, had a vision to create a sporting dynasty to rival NRL club the Brisbane Broncos.

But talk of a massive financial carrot being dangled by Melbourne Victory had the usually unflappable Postecoglou bristling yesterday.

Asked if speculation about his future was ''unfair'' with the club facing a crucial ACL match and grand final defence he fired: ''Do you [media] think it is, you keep asking the question, don't you?

''It doesn't matter what I say to be honest, we've got a grand final to win and a big game tomorrow night and that's all I am focusing on.''

Postecoglou's ability to get the best out of players and his high success rate has drawn comparisons with former Broncos coaching great Wayne Bennett.

''Where's Wayne now?'' he responded.

''It's not how sport works. I'm not saying I'm Wayne … this whole question about my future is something that fascinates other people, it doesn't fascinate me.

''I've never thought too far ahead, I never have and I never will.

''Our priority is here and our supporters have got a wonderful opportunity to see the side again this week in two massive games and I'm sure that's what they're excited about.''

Roar skipper Matt Smith said talk Postecoglou may walk out was not impacting on the players as they juggled two games in six days.

''Not at all,'' he said.

''I've been asked that question quite a bit over the last few weeks and until I hear from Ange, the Roar or someone involved in the club, as players we're focused on what we need to do.

''I can't change Ange's mind, I can't decide for him but I can certainly try to make sure we do the right things on the pitch.''

Postecoglou was clearly unimpressed when the question was raised near the end of the interview whether this week's results would impact on his decision.

''What decision?'' he said tersely.

''I keep saying the same thing, I'm not thinking about a decision, I'm thinking about tomorrow night.

''We want to win tomorrow night. We want to get through to the next stage of the ACL and we want to win the ACL.'' AAP
