Flyhalf Sacha Feinberg-Mngomezulu will be instrumental on the attack for the Springboks in the final Test of Rugby's Greatest Rivalry against the All Blacks on Saturday.

Several changes to the All Blacks side for the final Test of Rugby’s Greatest Rivalry against the Springboks mean some fresh mini-battles will take place as the sides clash in Baltimore on Saturday evening (11pm SA time).

The Boks will be wary of the experience brought back by their opponents, but should still have enough firepower to take the clash. However, a handful of New Zealanders could upset the apple cart at M&T Bank Stadium.

We look at five match-ups that could provide the spark in the finale.

The South African big man has scrummed every All Black opponent into the ground and now it’s the turn of De Groot again. Everyone will remember that first scrum at Ellis Park where Louw had the number of his opponent. His scrummaging will be key, but also his ball carries and setting the rolling maul of the Boks.
