Erasmus' appointment comes at a time when the two-time world champion Springboks have lost much of their aura after being humiliated 57-0 by New Zealand last year, the low point of a bad two years when they were also beaten by teams like Ireland, Argentina and Italy under Coetzee.
Since Allister Coetzee was sacked this month after winning only 11 of 25 Tests in two seasons, it has been accepted that South Africa director of rugby Erasmus will take over. After the departure of Heyneke Meyer in 2016, Rassie Erasmus was next in line for the Bok coaching job - even though as a coach, the only trophy Erasmus won was the Currie Cup more than a decade ago.
Jacques Nienaber, Pieter de Villiers and Mzwandile Stick will assist Erasmus, while Aled Walters will join the management team as Head of Athletic Performance. At the time, it had been expected that Erasmus would work alongside head coach Allister Coetzee, who was under contract until after the 2019 World Cup.
Walters, who has considerable worldwide experience gained from working in Australia, New Zealand and Ireland, joins the team from Irish side Munster, where he was their Head of Athletic Performance.
"The Springbok team is our flagship brand and the on-field performances have a direct impact on the business of SA Rugby", Roux said.
Newly appointed coach Rassie Erasmus says South Africa have the players to contest for the World Cup in Japan next year but adds they will have to buy into his methods fast to be successful.
While the Wales match falls outside of World Rugby's Test window, Erasmus said he needed to look at overseas-based players before next year's World Cup.
On the domestic scene he represented Free State and the Cats in Super Rugby before engineering the Cheetahs' first Currie Cup success in 29 years when he beat the Blue Bulls at Loftus as a player/coach.
"Following a very detailed review process of the 2017 season, I believe that we have managed to assemble a strong and experienced Springbok coaching and management staff".
Erasmus won 36 Test caps for South Africa and is relishing the prospect of coaching his country. "We are looking forward to see improved performances this season".
I have to point out a few things about Erasmus.
