Retallick has handled press duties with aplomb during the past two seasons and yesterday's stand-up in Napier as the countdown to Saturday night's test against Argentina at Napier's McLean Park continued was no different.
Retallick, who played 12 games for the Magpies during the 2010 and 2011 seasons, said the clash would be another huge test for the ABs tight five.
When quizzed on how the ABs would cope with the Pumas' much vaunted scrum, Retallick replied: "We've got to keep the pressure on after our little hit and go forward or at best hold it steady.
"It's different to how we would scrum against the Wallabies."
The 2011 New Zealand under-20 world champion is looking forward to marking Pumas lock Tomas Lavanini, who had a short training stint with the Chiefs this year.
"Tomas is definitely physical ... I've seen him knock someone out."
