Rassie Erasmus, Eddie Jones laud Sacha Feinberg-Mngomezulu after stellar Wembley display

The young flyhalf delivered another composed performance for the Boks in Saturday's 61-7 win, scoring 16 points through two tries and three conversions in his fourth consecutive Test start.

Erasmus was impressed with the way in which Feinberg-Mngomezulu imposed himself on the game, but once again stressed he was no overnight sensation, having worked his way through the Bok system over the past few years with the help of many guiding hands.

"We must remember that he has been with us since 2022, when we were touring Ireland and he was playing for the SA 'A' side versus Munster and Bristol. He comes through our EPD system," Erasmus explained.

"Everyone is viewing it as a rapid rise, but he's been working with all the different coaches through all the different stages. He trained with us for the entire end-of-year tour. Then obviously he is working with Manie (Libbok), Handre (Pollard), Mzwandile Stick, and Tony Brown."

While the Bok coach seems careful to limit the hype around the breakout young star, even he had to admit that Feinberg-Mngomezulu's performance against Japan was impressive.

"In a wet game like this, I thought he did really well. He was physical for a number 10, he kicked well, tackled well, and he's got the magic feel for the game. With him, Manie and Handre, we're in a fortunate position with our flyhalves."

Still, Erasmus is determined to keep his flyhalf's feet on the ground.

"He played against Ireland at home when we drew that series, and against the All Blacks away when we did pretty well. But we must never forget what Handre Pollard has done for us in crunch times, and what Manie did for us at the World Cup. The hype around him is not caused by him; it's caused by people. He's very level-headed.

"Obviously you can see Sacha is getting more comfortable, but we face France next week and Ireland later on tour, so we always need to make a step up."

Japan coach Eddie Jones offered his own glowing assessment of Feinberg-Mngomezulu, saying he gave the Boks a new attacking dimension and played a major role in their dominant kicking game.

"I'm impressed by his leg speed; he has got serious, quick feet, and he is a big guy at 10," Jones said. "He has got a fantastic fend too. He gives South Africa a different threat."

Jones noted that while the flyhalf still has areas to grow, "he is going to be one hell of a player" if he continues on his current trajectory.
