Argentine players celebrate after winning the rugby union Championship match between Argentina's Pumas and South Africa's Springboks.

With a return fixture to come next week, Erasmus has rested a couple of key figures, with Siya Kolisi in the coaches’ box rather than on the pitch as he manages a facial injury. Argentina may therefore spy an opportunity to cause a shock — the hosts are full of confidence after producing a record win against Australia a fortnight ago.

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.
