On Saturday, De Klerk will once again pit his wits against vastly experienced All Blacks scrumhalf Aaron Smith.
“We have become friends off the field, but we know that once we get on the pitch it's back to business. He is one of their key players with over a 100 Test matches — that makes him unbelievably successful with what he has been doing over there and it is always good to play with one of the best in the world.”
There are three other scrumhalves in the Boks squad in Jaden Hendrikse, Herschel Jantjies and Grant Williams. De Klerk said he enjoys the competition.
There is also Cobus Reinach who is out with a shoulder injury but expected to be fit for the back-to-back clashes against Australia Down Under next month.
