Despite everything learnt in Morocco during last year's fairytale campaign, and a squad bolstered by some handy acquisitions, the gulf in class, resources and experience is huge.
Coach Ramon Tribulietx said recently they were taking on a team in Japan "20 times bigger" and that's not too far from the truth.
Their opponents will be either Sanfrecce Hiroshima, who were also J-League champions in 2012 and 2013, or Gamba Osaka, who were champions last year and reached this season's Asian Champions League semifinals.
Hiroshima won the first leg of the final 3-2 at Osaka on Wednesday. The second leg was played overnight. Whoever qualifies will be match hardened, coming off a 36-game domestic season, followed by a playoff series.
Any chance Auckland City could sneak under the radar or be taken lightly would have been extinguished by their heroics last year.
But there are reasons for hope. Tribulietx has become a master at preparing teams to take on much more fancied opposition and their previous performances in Japan have been meritorious.
Auckland City also has a core of players who featured last year, including Angel Berlanga, Marko Dordevic, Takuya Iwata, Mario Bilen, Ryan DeVries and Jacob Spoonley. And they had a promising 1-1 result in a hit-out against J-League 2 side Yokohama on Friday.
"It was a good game and they gave us a good run-around. We really got the legs working," said defender Jesse Edge. "It was a good start by the boys. It dropped off in the second half but it was a good run-out overall."
Thursday's match is the 10th anniversary of New Zealand participation in the Club World Cup, which began with Auckland City in 2006.
