Australia or Argentina must do something miraculous on Saturday to rip the Tri Nations title from New Zealand's grasp.
With the All Blacks boasting a points differential of plus 64, the Wallabies need a bonus-point win with a margin of at least 101 points.
The task facing the Pumas, who also need a bonus point, is only slightly less daunting as Mario Ledesma's side must outscore their opponents by 93.
With such lofty targets to hit, this weekend's clash in Sydney is more about signing off from the competition in style than any remote prospect of actually winning it.
Nonetheless, these two sides drew in their meeting on matchday four, making it an intriguing fixture even if silverware is not realistically on the line.

Australia are enduring a tough time, with Dave Rennie's side having won only one of their previous six Tests, although that victory was against New Zealand on matchday two.
The Wallabies' record against the Pumas offers scope for encouragement for the hosts, who have lost just one of the teams' past 10 meetings.
Argentina have proven particularly stubborn in the first half of matches, conceding only one try before the break in their four games so far in the Tri Nations.
On the flip side, Ledesma's charges have allowed six second-half tries.
