Rassie Erasmus says it will take a proper 80-minute effort to win in Buenos Aires on Saturday. Springbok coach Rassie Erasmus is expecting a blockbuster encounter against Argentina when the two sides collide in a one-off Test at the Estadio José Amalfitani in Buenos Aires on Saturday night (9pm SA time). Their passion and patriotism for their country and people, and the way they give everything on the field and keep fighting is a testament to the type of Test match we are expecting this weekend,” said Erasmus. “They have a strong forward pack and dangerous backs, and they will have a very passionate crowd behind them, so we will have to be at our best to win this match. “We’ve had to grind out results against them on several occasions in the past, so it will take a proper 80-minute effort this weekend, and we are looking forward to the challenge.”
