City enter Sunday's elimination final as favourites courtesy of their home advantage at AAMI Park, yet that doesn't tell the whole story.
Zero home-and-away wins against Glory, including a ridiculous 5-4 loss in Perth four days ago, have put City on the back foot and given Kenny Lowe's side a timely injection of confidence.
In addition, Djulbic said the squad were in a different headspace to this time last campaign, when City bundled them out at the same venue.
"The last game of last season was against Sydney FC and we got thumped 4-0, so I think confidence was a little bit down," Djulbic said.
"This time we've won the last two games so we're full of confidence. We want to take that into the game.
"I think it's a psychological thing against them as well, that we've beaten them just seven days ago - that's an advantage.
"Everyone's buzzing, so hopefully we can go there and cause some havoc."
The key once on the pitch, Djulbic says, will be to score early.
That shouldn't be an issue given Glory have six goals from their last two visits to AAMI Park and have netted a league-high 10 in the opening 15 minutes of games this season.
"The aim is to start strong again," Djulbic said.
"Usually when we do that we finish the game on a high as well.
"It will be very important to score the first goal, so hopefully we can pinch one early again."
The firepower of Andy Keogh, Diego Castro and Adam Taggart with 12 goals apiece has been a central component of Perth's success.
That said, their open style has meant they've conceded with much the same enthusiasm, with exactly 53 goals each way.
Djulbic will again have his hands full with City's star frontmen Bruno Fornaroli and Tim Cahill, a challenge the 34-year-old centre-back relishes.
"I love playing against good, big players because it brings the best out of me," he said.
"We're working on defending this week in training more, we know what they do so we've just got to try and minimise it."
