England attacking skills coach Mike Catt has urged the team to expect a backlash from South Africa when they meet at Twickenham Stadium on Saturday.
The Springboks head into the match on the back of a shock 29-15 defeat against Ireland in Dublin last weekend.
However, Catt is adamant that the tourists will be desperate to get back to winning ways when they go head to head with England.
"The bounce back from South Africa is always huge," the former fly-half told Sky Sports News. "It is always a massively physical encounter.
"The beauty about the South African side is they have the ability to do all of it. When they come to Twickenham, they will see this as the main scalp they need to take."
England lost their opening Autumn International 21-24 to world champions New Zealand last weekend.
