South Africa coach Erasmus wary of struggling Argentina

South Africa head coach Rassie Erasmus insists the world champions face a “massive challenge” against Argentina on Saturday despite the recent poor form of their opponents.

The Springboks stretched a winning Test run to 11 matches with home victories over England, Scotland and Wales during July in the inaugural Nations Championship.

Facing the same northen hemisphere teams in South America, the Pumas beat Wales, but lost to Scotland, and England in an ill-tempered clash.

Argentina thought they had scored a late try against England, giving them a chance to draw the Test.

When Australian referee Angus Gardner disallowed it after a lengthy review, Pumas fly-half Tomas Albornoz was furious.

The playmaker had to be physically restrained by a teammate and coaches as he remonstrated with the match official and has since been banned for four matches, starting with the Springboks.
