Argentina coach Mario Ledesma has precious little time to fix his side's backpedalling scrum if they are to have an impact at the Rugby World Cup in two months' time.
The Pumas were unable to compete with a Wallabies scrum that Ledesma himself had rebuilt when he was the team's forwards coach under Michael Cheika in their 16-10 Rugby Championship loss in Brisbane.
Ledesma, however, was bemoaning his side's inability to match it with Wallabies starters Scott Sio and Sekope Kepu before James Slipper and Taniela Tupou came on in the second half and kept the pressure on to earn a spate of scrum penalties.
Australia's scrum also provided them with the foundation for Reece Hodge's first-half try.
"My concern was much more the set-piece," Ledesma said of the scrum's woes.
