The Socceroos must beat Peru when they meet in Sochi at the World Cup if they're any hope of progressing to the round of 16.
While they'll also need France to defeat Denmark, Australia must first find a way past an unlucky and dangerous Peruvian outfit that will be looking to depart Russia with something to show for their efforts.
Peru have suffered narrow 1-0 defeats in both of their group games and will not be easy pickings for a Socceroos side short on goals.
With Mile Jedinak penalties the only way Australia have found the back of the net at the World Cup to date, they need their starting striker to stand up against Peru.
Andrew Nabbout has led the line in both games so far, but having dislocated his shoulder against Denmark is unlikely to start, let alone play.
As such, Goal looks at the Socceroos candidates to lead the line against Peru.
Tomi Juric suffered a knee injury during Australia's training camp prior to the World Cup and has had to settle for a substitute role so far in Russia.
He was the Socceroos main starting striker during qualification but has struggled to make the most of his chances in front of goal.
Netting just five goals across 16 qualifiers, Juric failed to make the number nine spot his own with Tim Cahill turned to for a crunch play-off against Syria.
A well-built forward that is particularly good at holding the ball up and utilising his wingers, Juric looms as an ideal outlet against Peru.
With winger Matthew Leckie starring against Denmark and young gun Daniel Arzani closing in on a starting spot on the left flank, it'll be crucial both are brought into the game and Juric could be the key to that.
Standing tall at 189cm, Juric is the tallest striker Australia has in Russia and that height could come in handy against a Peruvian outfit better on the ball than in the air.
Only brought back into the squad as a result of Juric's injury, Jamie Maclaren is yet to play a minute at the World Cup and will be desperate to show why he was worth recalling.
A terrific end to his club season with Hibernian left the 24-year-old in good form leading up to Russia and reports from inside Socceroos camp is that he's been one of the sharpest players in front of goal in training.
A pacey poacher by trade, Maclaren is capable of darting past a speedy Peruvian back line and popping up at the right time inside the box.
With only a handful of caps for the Socceroos so far, he is yet to score for Australia and a debut goal in the World Cup would make for a particularly special moment.
The two goals Peru have conceded to date have come as a result of sloppy turnovers with Maclaren a player that can make any side pay for such mistakes.
Their was national outrage when he wasn't brought on against Denmark and Tim Cahill's involvement against Peru is again no certainty.
With very few club minutes under his belt over the past season, the 38-year-old is at odds to start for the Socceroos but is a weapon that will likely need to be deployed off the bench at some stage.
Looking to become just the fifth player in history to score at a World Cup, Cahill has added motivation to strike in Russia and will be hard to overlook against Peru.
If a goal is needed with half an hour to play, Bert van Marwijk will be hard pressed not to turn to Cahill, who has a knack of popping up when he's most needed.
From scoring the Socceroos first World Cup goal to heading home an extra-time winner against Syria, the striker can still deliver and deserves the chance to secure a fitting farewell from the national arena.
A dislocated shoulder against Denmark has seemingly ended Andrew Nabbout's World Cup campaign, but the player himself remains intent on playing his part against Peru.
Even if he is to overcome the injury in time, a change up top is needed with Nabbout tireless but largely anonymous for Australia to date as a number nine.
While he's done exactly what Bert van Marwijk has wanted from him, Nabbout is a winger by nature and the Socceroos now need an out-and-out striker.
If he is fit, Nabbout could prove handy off the bench being deployed on the wing or even as a back-up striker should Australia be that desperate for goals.
