Cape Town - The Jaguares showed against the Cheetahs last weekend that, like the Argentinean national side, they are not afraid of getting stuck in.
At one stage they were down to 13 men in Bloemfontein, and Sharks captain Beast Mtawarira is expecting a stern test of his side's discipline at King's Park on Saturday night.
"A good start is very important. You have to get in to their faces early," the Springbok loosehead said.
"They’re the kind of guys that try and niggle you from the start and try and get under your skin.
"It’s about keeping our cool and making sure that we’re aggressive in our tackling and breakdowns without giving away stupid penalties."
Mtawarira is also expecting a massive battle at scrum time.
"It’s always a formidable challenge when you go up against the Argies," he said.
"They’ve got a big scrumming mentality so I think it’s something that we know about.
"The Cheetahs really stepped up and did well against them. We’re going to stick to our own processes and focus on ourselves."
The Sharks beats the Kings 43-8 last weekend while the Jaguares beat the Cheetahs 34-33.
Kick-off on Saturday is at 19:20.
