Sydney FC humiliated great rivals Melbourne Victory with a 6-1 A-League semi-final win to qualify for next week's decider against Perth Glory.
The Sky Blues scored three times in each half at Jubilee Stadium to claim their biggest win in the Big Blue and gain some measure of revenge for what happened to them last season.
Victory beat them 3-2 after extra time a year ago at the same stage in a controversial game, denying Graham Arnold the chance to bow out by winning the A-League treble.
While the Sky Blues had avoided talking of revenge in the lead-up to the semi-final, they did admit after the stunning win that it had been a factor for them.
"I did mention it in the changing room before we went out," said coach Steve Corica. "I've kept it quiet all week but there's a lot of boys that were there last year and it obviously hurt us to lose the way we did – they wanted to put it right and they did that tonight."
Things went badly for Victory from the start, their usually reliable keeper Lawrence Thomas dropping a corner in the third minute and seeing the ball cross the line off Aaron Calver.
Although Sydney FC had to wait almost until half-time to add to their lead, the fact that they netted twice in the final few minutes of the half gave them a healthy cushion.
Alex Brosque netted from close range to double their advantage and, in injury time, a shot deflected past Thomas off Leigh Broxham for an own goal to send the home supporters into ecstasy.
It was impossible at that stage to see a way back for Victory and, when they let in two more goals in the space of five minutes midway through the second half, the rest of the match was academic.
Adam Le Fondre netted the first from the penalty spot, having been brought down in the area, and the English striker was again on target to make it 5-0.
Le Fondre had ended the regular season second in the A-League Golden Boot standings with 16 goals, two behind Wellington Phoenix's Roy Krishna.
Two minutes from time Milos Ninkovic added a sixth goal for the home side to further embarrass Victory and Swede Ola Toivonen did not celebrate when he headed home for Muscat's team in injury time.
Sydney FC are 1/1 to win the Grand Final, with Perth Glory 4/5. The Sky Blues are 19/10 to win in 90 minutes, with Perth 7/5 and the draw 12/5.
