South Africa coach Heyneke Meyer believes his side can do the impossible and pip New Zealand to the Rugby Championship crown.
The All Blacks are on the brink of defending their title, having won all five of their matches - including a 29-15 win over the Springboks at Eden Park.
That means the Boks need to score at least four tries and hope that the All Blacks don't pick up a bonus point if they are to finish the competition on top.
And Meyer insists his side will not play it safe as they look to upset the odds at Ellis Park.
"I really want the team to go and score four tries," said Meyer. "By saying that it is a huge, huge challenge because the more rugby you play, the All Blacks play off your mistakes.
"I believe you can't be in two minds. You are either going to go for the four tries or play it safe and try and win the game.
"No one will probably give us a chance but it is just great to go positive into this game and try to do what's impossible."
South Africa boast an impressive record at Ellis Park against the All Blacks, though, having won eight of the 11 meetings between the two sides there.
That includes the 1995 Rugby World Cup final, when Joel Stansky kicked the Boks to a 15-12 extra-time victory.
Scoring tries at the ground against the world champions hasn't been an issue either, with 11 in their last two matches there.
South Africa v New Zealand will be live on Sky Sports 4 HD, with coverage beginning at 3pm on Saturday.
