Twickenham stages a finale that is part decider and part examination of identity. South Africa strode in from Durban after a ten-try statement that reminded everyone of their ability to turn pressure into points in violent bursts.
Argentina arrive with a reset, wounded but not broken, and with a selection that suggests width, ambition and a refusal to accept that last week defines them.
There is history in this ground for both. South Africa has banked big wins here and usually looks at home on the broad surface. Argentina have tasted victory over England at this stadium and understands the rhythm of the place. The equation is simple. South Africa wants to roll their maul, bully the scrum and let a young fly half conduct. Argentina want to stand up at set pieces, keep discipline, and hit space through speed.
2025 FloRugby Athlete’s Lounge – Oct. 4
Argentina vs. South Africa Rugby Team News
Rassie Erasmus sticks to a strong core and makes smart tweaks. Ox Nche returns at loosehead to join Malcolm Marx and Thomas du Toit. Eben Etzebeth partners Ruan Nortje in the second row, with Siya Kolisi, Pieter Steph du Toit and Jasper Wiese in a back row built for collisions.
Cobus Reinach starts at nine, and Sacha Feinberg-Mngomezulu continues at ten after his record-breaking outing in Durban. Damian de Allende and Canan Moodie form the midfield, Cheslin Kolbe and Ethan Hooker start on the wings, and Damian Willemse is at fullback.
The bench brings impact in line with the Boks’ ‘Bomb Squad’ mantra with Bongi Mbonambi, Jan Hendrik Wessels, Wilco Louw, RG Snyman, Kwagga Smith, Grant Williams, Manie Libbok and Jesse Kriel.
Felipe Contepomi responds with seven changes. Santiago Carreras moves to fullback to stabilise the back field and add a second playmaker. Juan Cruz Mallia starts on the wing, Justo Piccardo comes into outside centre, and Bautista Delguy returns on the right.
Geronimo Prisciantelli is given the ten jersey beside Simón Benitez Cruz. In the pack, Guido Petti and Pedro Rubiolo pair at lock, and Santiago Grondona comes in at eight.
Julian Montoya continues as captain and reaches a remarkable landmark for caps as skipper. The bench features Ignacio Ruiz, Boris Wenger, Francisco Coria Marchetti, Franco Molina, Juan Gonzalez, Joaquin Oviedo, Agustin Moyano and Rodrigo Isgro.
Los Pumas vs. Springboks Key Match Up
Start with the scrum. Ox Nche and Thomas du Toit against Mayco Vivas and Joel Sclavi will set the tone before the clock ticks past five minutes. Durban tilted when South Africa established dominance at the set piece, and two of those penalties became immediate points. Nche has the low body angle and hip power to drive straight. Du Toit is a pressure athlete who can turn one strong engagement into a trend. If Argentina cannot anchor here, they will be forced into a kick-only strategy, and that invites South Africa to play in the right areas with the scoreboard ticking.
Then consider the tens. Feinberg Mngomezulu was the story of Round Five. Three tries, a flawless goal-kicking ledger and a calm orchestration that belied his age. He does not play like a pure distributor or a pure runner. He plays like a conductor who understands when to accelerate and when to let the pack crush the air out of a contest. Prisciantelli is stepping into the deepest of waters. He has the skill to clip long passes across a rushing defence, and he has a good feel for the kick pass to the edges. His challenge is time. The Springbok rush denies it. If he creates some, Argentina can challenge. If he cannot, the pressure will compound.
Finally, the back rows. Kolisi and Pieter Steph du Toit bring the standard South African work rate and heavy collisions, while Wiese ensures momentum through the tackle. Argentina counters with the ferocity of Marcos Kremer and the nous of Pablo Matera, who remains the tone setter when he is on the field. The team that wins the first three rucks of a possession sequence will create the chances they want. The team that loses those rucks will be trapped in their own half by the Bok boot.
Argentina vs. South Africa Rugby Key Stats From Round 5
Durban was not subtle. South Africa scored ten tries and ran the Pumas off their feet after a competitive first half. Sacha Feinberg Mngomezulu broke an eighteen-year Springbok record for individual points in a Test and did so while looking like the most relaxed player on the field. Malcolm Marx and Pieter Steph du Toit were also on the scoreboard, and the Springbok bench arrived to slam the door. Argentina had moments, especially through Joaquin Oviedo, who carried with edge and through Juan Cruz Mallia, who found seams from the back, but they could not stitch enough phases together to sustain pressure.
The trends from across the Championship tell the same story. South Africa has been the most efficient team when they enter the opposition twenty-two, and they have conceded the fewest clean breaks. Argentina have lived on the edge in discipline, conceding more penalties than anyone else and feeding opponents a diet of field position that good teams feast on. Lineout accuracy has also been a pressure point for the Pumas. When Julian Montoya hits his jumpers, they can build, but the misses have been costly. The Springboks, by contrast, have turned lineout possession into maul platforms and then into tries in almost every round.
What History Tells Us About Los Pumas vs. Springboks
The rivalry favours green and gold. South Africa has won the vast majority of meetings between the teams and has been especially strong away from home. Argentina have taken notable scalps in this Championship and in recent seasons, including in New Zealand and against the British and Irish Lions, but the Springboks remain their hardest puzzle. The only previous meeting between these teams in London was the bronze final of the 2015 World Cup, where South Africa won with control. Twickenham, therefore, carries good memories for Kolisi’s side. For Argentina, it is a chance to redraw that picture against the most physically complete team in the sport.
Argentina vs. South Africa Tactical Focus
Erasmus will keep the menu simple. Dominate scrum and maul. Kick to the corners. Strangle territory. Then give the backline permission to play once the defence narrows. Reinach will snipe only when the guard is late. Feinberg Mngomezulu will drop in and out of first receiver to free Willemse and de Allende to carry hard lines. Kolbe will search for mismatches and short kick space behind a rushing wing. If South Africa reach a plus penalty count early, the rest will look inevitable.
“It’s about the other 21 hours in the day.”

Contepomi will ask for variety. Contest the lineout through Guido Petti. Aim for longer exits that find touch and remove South Africa’s counterattack. Look for Chocobares to attack the inside shoulder of the first forward guard and for Delguy to test the edges when the Springbok line widens. The Pumas must choose the right times to run. If they turn over possession in the middle third, South Africa will turn it into points in three phases. If they pick their moments, they have the athletes to stress the Bok defence.
Argentina vs. Springboks Prediction
The Springboks are built for days like this, and their form backs the selection. Expect the scrum to bite early, the maul to draw penalties, and the points to come in steady waves through the third quarter. Argentina have threats and they will produce moments, but unless they find unexpected parity at set piece the gap will widen. Call it South Africa 38 to Argentina 23, and a second straight title sealed with authority at Twickenham. South Africa by fifteen.
