South Africa head coach Heyneke Meyer has admitted that he expects an England backlash when the two sides meet at Twickenham on Saturday.
The Springboks enter the match off the back of a 21-10 win over Scotland, while England were beaten 20-14 by Australia at the weekend.
"England will be even more motivated [after the defeat]. Saturday will be the ultimate test. England has a great team and we've got a lot of respect for them," he told the BBC.
Meyer has been in charge of South Africa since January 2012.
