Andy Farrell will invoke the spirit of Port Elizabeth as he steels England's wounded men to meet the ferocious South African challenge at Twickenham on Saturday.
After being on the receiving end of two brutal defeats on the summer tour, England met the Springbok physicality head-on in the third Test and emerged with a creditable 18-18 draw.
"We've got to remind the team of Port Elizabeth," said Farrell, England's assistant coach. "In that game we took our defensive game to them and that is how it has got to be this weekend."
He added: "There was a fighting spirit in that game. It shone out massively, you could see our intent to not let South Africa do what they do best, which is batter the gainline door down.
"We did it well that day."
England were disappointed not to emerge from the Port Elizabeth Test with a win - but the Springboks were angry.
South Africa coach Heyneke Meyer told the team they had let their country down by not completing a clean sweep of Test victories over an inexperienced England side.
While the Springboks are unlikely to unleash a box of attacking tricks like the Wallabies last week, Farrell would not be surprised if they bring out something new at Twickenham.
"The South Africans were pretty annoyed to draw that game," Farrell said. "They realised we were good that day, we got among them and got stuck in and I'm sure they will pick a team to combat that.
"South Africa have a way of playing, they don't change much and they have some big boys. But they will have a few intricacies. You have to expect the unexpected."
