With one round to go in the Rugby Championship, we run through the permutations of the final weekend as the Springboks and Argentina hunt for the title.

Argentina have now beaten all three Rugby Championship opponents after they triumphed over the Springboks 29-28 in Santiago. The hosts scored four tries on the day with Mateo Carreras, Pablo Matera, Joel Sclavi and Tomas Albornoz scoring with the fly-half also kicking three conversions and a penalty in an epic shift.

A group still led by Pablo Matera will have to match South Africa today. The visitors are without four of their regular starting five at the back of the scrum - if Argentina can get on top of that remodelled group at the breakdown and dominate the lineout, a shock could very well be on the cards.
