The Reds  coach joked that he would be parking a bus in front of the goal to stop Victory from scoring.

He said: "It's a double decker by the way. I don't want to talk about their two boys up front, they just know where the goals are. We know it's going to be very tough, we need to play tough and smart football and we need everyone to do that.

"It's 50-50, it's 90 minutes of football, certainly we need to improve on the performance we had against them in the major semi-finals, and I don't think we can play that bad again."

Vidmar said he had already decided on his starting XI and there was unlikely to be many changes from the team which defeated Queensland last week.

He said: "That team did quite well, considering everyone's under a little bit of pressure to get a result. The team did very well. There's no need to change it.

"I've decided it, that will be kept between myself and the team and that will be announced just before the game."

Adelaide have pinpointed the space Melbourne were allowed in the midfield as a major factor in the two semi-final losses. Vidmar addressed that by putting Jonas Salley in as a second holding midfielder against  Roar, and it worked very well. He is likely to go with the same ploy this week.

He said: "That's certainly an area where they were very strong and they were very poor in those two games. That's an area we need to make sure we get it right."

Adelaide have already lost a final this season, going down to Japanese giants Gamba Osaka in the decider of the Asian Champions League. Vidmar said that while a loss on Saturday would not condemn the season as a failure, the club will be judged on the trophies they win, not the finals they made.

He said: "It's been a tough season for us. We've had a lot of football, we've played a lot of big games. One's that take mental and physical strain out of us.

"At the end of the day, it's all about silverware. They'll say it's not successful unless you win some silverware and tomorrow night's an opportunity to pick up a trophy."

However, Vidmar praised the steps the club had taken in the past 12 months after missing the finals last year.

"It's delivered a lot, you have to remember where we came from last year, we didn't make the finals, we finished sixth, we had a lot of young kids. From where we have come to achieve what we have this year has been a massive turnaround," he said.
