'Eddie will have something up his sleeve' as Bok assistant coach Davids ahead of England Test.

In London

Springbok assistant coach Deon Davids said England coach Eddie Jones's ingenuity and inventiveness are just a few of the challenges they need to combat when they face England at Twickenham on Saturday.

On a cold and rainy afternoon at the Boks' Lensbury Hotel base in Teddington, Davids admitted Jones's general tactical and selection sharpness, with the former Australian head coach hinting at picking Maro Itoje at blindside flank to make way for South African-born Dave Ribbans to start at lock alongside Jonny Hill.

Such a change is ostensibly geared to challenge the Boks' lineout and maul, which was slightly faulty against Ireland and France, but came good against Italy.

Davids said they need to be in a position to react to anything England will throw at them.

"Eddie's a good coach who always has something up his sleeve, so we're not expecting anything different for this game," Davids said.

"We need to be spot on in terms of our focus and how we will react to the challenges that they'll bring to us.

"We always prepare for a difficult encounter at Twickenham."

England goes into the Test on the back of a rousing 25-25 draw against the All Blacks where they reeled in a 19-point deficit in the last 10 minutes.

England had shown flashes of brilliance throughout the second half after a slow start, but how they took charge at the back end was frightening and fascinating.

The Boks, who haven't won at Twickenham since 2014 and lost their last two fixtures there against England by a point, are well aware of England's noted resilience at home against the Southern Hemisphere teams.
