Hammered 4-0 by arch rival the Brisbane Strikers and 3-1 by the Brisbane Roar Youth side in the past fortnight, the fourth-placed Fire needs to get back on track and create some breathing space between it and teams below.
Third-placed rival Olympic FC faces a difficult outing against ladder-leading Moreton Bay United, opening the door for the Fire to narrow the margin on Olympic and further the gap to fifth-placed Palm Beach.
Fire skipper and tireless winger Reyze Kelly said his players were treating tomorrow afternoon's clash in Newmarket as a must-win match, desperate to firmly establish themselves in the finals frame.
"Going through a tough patch like that (the past fortnight) is always difficult, without a doubt," Kelly said.
"Every game we treat as a must-win, but this in particular - if we get a win here we can get closer to third place and distance ourselves from the rest of the pack."
The Fire spanked City 6-0 at Sunshine Coast Stadium in the first round of the season.
Kelly will be hoping history repeats tomorrow, having bagged himself a goal against City and seen youngsters Brady Cronk and Jacob Fulluck each nab a brace.
"We're looking for some consistency to come again," he said.
Kelly said the team had been boosted by the knowledge that experienced player-coach Paul Arnison was available to take the field when required.
He conceded though that his side had been forced to put aside disappointment at not getting a chance to tackle Kawana midweek in the FFA Cup.
That game was postponed for an investigation into Kawana's alleged use of an ineligible player.
"We were pretty excited for the FFA Cup game - they're always tough, physical games," Kelly said.
"We were all pumped up for it so it was a little bit upsetting, but once we heard that was the case it was back to business preparing for this weekend."
Kelly said he was also looking to build on his own consistency to help the young Coast side to a finals berth that many predicted would be a step too far for the Fire this season.
