The Phoenix managed to grab a draw with a late Paul Ifill goal against the Melbourne Victory on Saturday night and will be out to get a win when they meet Necevski and the Sky Blues at Sydney Football Stadium.
But the in-form gloveman says the reigning champs will be ready to do whatever they have to record a win of their own.
"We've got to run, scrap, fight and make sure those three points are ours after the ninety minutes because they are going to come here fired up," Necevski said.
"They are coming off a point against the Victory so they will be hungry. Us coming off a short turnaround shouldn't be a problem so we will be ready come Wednesday night.
"We have recovered well so we will be fresh."
