Eddie Jones wants England to take a leaf out of Muhammad Ali's book as they prepare for a "physical game of chess" against South Africa at Twickenham on Saturday.
It is 10 years since England have beaten the Springboks, but the Six Nations champions will start as strong favourites in their first autumn international this weekend.
Jones is well aware what to expect from Allister Coetzee's side and warned England must not play into the Springboks' hands.
"When Muhammad Ali fought George Foreman, he had to find ways of getting around him," said the England head coach.
"Playing against a physically aggressive side, you have to play smart.
"You don't want to go wide against South Africa because that is what they want, South Africa were the originators of rush defence, so we have to be smart about how we use the ball.
"It is about contesting that first set piece, we have to make sure South Africa don't win the ball."
He added: "South Africa are a very structured side, they play the game like a physical game of chess.
"They know exactly where they want to go and they do it with force, and so we have to be good at not letting them win the ball in the right place and on that second and third phase, not letting them get momentum."
