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.

The Boks have never won six in a row in the Rugby Championship, and they've never won the tournament with a match to spare, but they have the opportunity to achieve both of these feats against Argentina in Santiago del Estero on Saturday and turn next weekend's finale against the Pumas in Nelspruit into a celebratory affair.
