That's the feeling lock Scott Barrett, 45 Tests, has ahead of the game.
The South Americans, who have endured more obstacles than any of their Championship opponents in arriving at the tournament, have not scored a point against the All Blacks in the two outings since last year's triumph when winning their first Test against them.
That would add to the desperation they brought to the Test.
"They'll look at their tape and present different pictures. They'll probably turn up with a little more of an edge," he said.
But while the Pumas would be looking to get better, so would the All Blacks.
Their review of their 39-0 win had not been short of areas where they could get better. They were focusing on those areas and looking to improve, he said.
The lineout boffins have had plenty to occupy them as they attempt to find a way to secure their ball from longer throws to the line. Argentina had been high nuisance value on Sunday in shutting off an avenue of attack for the All Blacks off throws to the back of the lineout.
At the same time, the All Blacks had realised the need to change. They threw to the front and were still able to dominate the lineout count.
"They were pretty structured, and disciplined, in their system, shutting off the back and middle areas of the lineout which is the best ball to launch from. We adapted as the game went on and had to win ball in other areas that are not probably what the backs want," he said.
While not giving away details of how they could achieve a change, Barrett said, "We're going to have to adjust to the way they defend.
"We can't get too carried away with trying to jump on their big, tall men – we've got to find the space and take it," he said.
