The Rugby Championship returned with a bang last weekend.
World champions South Africa stated their intent from the very start, dishing out a 33-7 thrashing to end Australia's unbeaten run under Joe Schmidt.
Meanwhile, New Zealand's crown could be under threat after they suffered an opening day slip-up as Argentina pounced, upsetting the All Blacks with a 38-30 victory.
Australia and New Zealand have a chance to right those wrongs on matchday two, while South Africa and Argentina will be looking to pull clear at the top of the table.
Here, we run through the best Opta stats ahead of this weekend's action, picking out the players to watch in each contest.
NEW ZEALAND V ARGENTINA
New Zealand's defence of their Rugby Championship title did not get off to the desired start as they let their half-time lead slip to lose to Argentina in Wellington last weekend, ending head coach Scott Robertson's perfect start.
However, they will be stepping out in Auckland this time around, a happy hunting ground for them as they are undefeated across their last 51 Test matches there (49 wins, two draws), scoring an average of 36.7 points per game across that span. Their last defeat in the city was a 20-23 loss against France in July 1994.
New Zealand also won their only previous meeting with Argentina at Eden Park, cruising to a 33-10 victory in the 2011 Rugby World Cup quarter-finals.
They bring plenty of physicality too, having made 11 offloads in the first round, the most of any team; the All Blacks have logged more than 10 offloads in their last two matches in the competition after doing so only once across their previous nine games in the tournament beforehand.
Argentina, meanwhile, won their Rugby Championship opener for the first time, having lost it in their previous 11 appearances.
And, after coming from behind to win that game, they look to have a new lease of life under Felipe Contepomi as they aim to get back-to-back wins over New Zealand for the first time.
Indeed, Los Pumas have won each of their last two Test matches against tier one opposition (38-30 v New Zealand and 33-25 v France) - the last time they recorded a longer winning run in such fixtures was a three-match span at the 2007 Rugby World Cup (v France, Ireland and Scotland).
Argentina made 183 tackles in round one of the Rugby Championship, the most of any team; it is the third time they have logged 180+ in a match in the tournament since the beginning of 2021 – Australia (twice) are the only other team to have done so more than once in that time.
PLAYERS TO WATCH
New Zealand – Ethan Blackadder
Despite being on the wrong end of the scoreline, Blackadder managed to catch the eye as he completed 20 tackles in round one of the Rugby Championship, the most of any player.
In fact, it was the joint-most he has made in a Test match for the All Blacks (also 20 v Ireland in November 2021).
Argentina – Matteo Carreras
While Agustin Creevy stole the headlines during Argentina's win last weekend, Matteo Carreras' involvement was equally important.
He has scored three tries in his last two Test matches, including one try against New Zealand last time out, as many as he scored in his eight Tests prior to that run combined (three).
AUSTRALIA V SOUTH AFRICA
South Africa started as they mean to go on with their statement win over Australia last weekend, and they have now won their last three Test matches against the Wallabies by an average margin of 24.3 points.
The last time the Springboks recorded a longer winning run against the Wallabies was a seven-match span from August 1969 to August 1971.
Indeed, South Africa have won each of their last two Test matches against their opponents in Australia, conceding no more than eight points on the day in either of those two wins.
South Africa's form anywhere away from home is impressive enough. They have won each of their last six Test matches outside their country, with three of those six victories coming by a single-point margin on the day. The last time the Springboks recorded a longer winning run outside the country was a nine-match span from August to November in 2007.
Rassie Erasmus' side completely dominated as they gained 547 metres on matchday one of the Rugby Championship, 149 metres more than the team with the second most (Argentina – 398); only once across their last 22 matches in the competition prior have the Springboks gained more in a game (698 v Australia in July 2023).
Schmidt's hopes of a strong start to the tournament quickly evaporated in Brisbane, but a move to Perth could be a good boost for their confidence, with Australia only losing one of their last nine Test matches in the city (winning seven, drawing one).
Australia won 20 line-outs (inc. two steals) in round one of the Rugby Championship, the most of any team; only once across their last 40 Test matches prior to that game had the Wallabies logged as many (20, inc. four steals v Fiji in September 2023). If they can make those count, they could give themselves a chance.
PLAYERS TO WATCH
Australia – Harry Wilson
While Australia's attacking play left much to be desired, Harry Wilson provided them with a driving force as he crossed the gainline on 10 carries on matchday one, the second most of any player (Ardie Savea, 12).
He also won seven line-outs, the most of any player in the opening round of the tournament.
South Africa – Kurt-Lee Arendse
Kurt-Lee Arendse continued his impressive run of form with two tries against Australia last time out, meaning he has now scored four tries in his last four Test matches.
He has scored five tries in his two career appearances against the Wallabies, scoring a hat-trick against them last year in addition to last week's brace.
