"But this time they [the All Blacks] feel the pressure - they have not won a World Cup in a while. To beat them, we will have to give 110 per cent in every department. If we do this, it is achievable.
"We can not take it too dramatically; it is only a game of rugby. Playing against New Zealand in New Zealand at a World Cup is once-in-a-lifetime."
Pichot steered the Pumas to third place at the Rugby World Cup in France in 2007, an achievement he felt was unlikely to be topped by this year's team.
Before the tournament, he downplayed Argentina's chances, saying the side's preparation - one test in 11 months - was insufficient for a title challenge.
"Qualification [for the quarter-finals] was the first goal. But I will be disappointed if I see the guys get battered on Sunday."
Now working behind the scenes as director of the Argentine union's high-performance board, Pichot said he was looking forward to enjoying the tournament without the stress of captaining the side.
He also intended to visit his friend Jonah Lomu in Auckland City Hospital, where the All Black legend is having treatment for problems with his transplanted kidney.
Pichot was among a plane-load of Argentines who told the Herald they have not travelled across the Pacific to watch a single match.
"We're not here for sightseeing," said one supporter at Auckland Airport. "We came to make this jetlag worthwhile - to win."
