The trio have been limited from playing together but joined up with locks Alun Wyn Jones and Bradley Davies to impress against the Australian forwards despite going down 25-16.

And McBryde is confident that they can put in a repeat performance against the Springboks – a side he believes are still coming to terms with new refereeing interpretations.

"We've traditionally started slowly in the autumn and built as the series went on, but we've really laid a platform," said McBryde.

"We always aim to dominate up front, that's what we're trying to achieve, having the scrum as a weapon.

"Everyone's settling down to the new law interpretations, they're quite consistent now so every team can build. We can now call the scrum a weapon again and use it.

"Out of the three big southern hemisphere teams, perhaps they [South Africa] are the ones who have adapted slowest to the new interpretations of the law and the way the game has gone.

"There are different strengths and weaknesses with every team. We adapted against Australia and made some subtle changes to our game plan.

"South Africa pose different threats. It is much more of a physical, direct threat. We've got to tailor our approach in attack and defence to match South Africa.

"I am sure they will have worked very hard behind the scenes to make up the ground lost, in the eyes of some, on New Zealand and Australia, and they will be looking to adapt their game likewise. They looked pretty comfortable in the win over Ireland [last Saturday]."
