"We won't be playing any differently than we were playing in the previous games," De Villiers told reporters on Friday. "Our game plan hasn't changed. I think to be successful tomorrow we have to execute what we have been doing."
De Villiers said the side were confident that the mixture of brute force up front and fast backs out wide that has taken them to 10 wins in 11 Tests since they lost to the All Blacks in last year's Rugby Championship would be the right approach again.
"We have to put up a performance like we did for the first 20 minutes last week and we need to do it for 80 minutes," De Villiers said.
De Villiers completes amazing comeback to captain Boks against Argentina
The Springboks bamboozled Australia in the first quarter of their 28-8 victory in Cape Town last week, scoring two tries, but then let their intensity drop to miss out on what could prove to be a crucial bonus point.
They need to score four tries and win by seven points if they are to wrest the four-nations tournament title away from New Zealand.
"The fact of the matter is that it is not a Mickey Mouse team we are up against tomorrow," De Villiers added. "They are the World Cup winners, the number one team in the world and they also want to win the competition, they want to win the game.
"It makes for a great game. We won't change anything but hopefully we can execute well tomorrow.
"This year has been really good, we have only lost the one game. It does come down to tomorrow's game... not so much the scoreboard but the way we play."
