All you need to know ahead of the second test between the All Blacks and the Pumas at FMG Stadium in Hamilton on Saturday, 3 September (kickoff at 7.05pm):

The All Blacks face another challenging Rugby Championship test against Argentina on Saturday, desperate to halt a three-match losing streak at home while fans go through stages of despair over the worst slump in the team's 119-year history.

New Zealand incurred losses to Ireland and France at the end of last season, then lost at home to Ireland for the first time and went on to lose that series. Then the All Blacks lost to South Africa, then for the first time at home to Argentina.

That's shifted the mood of fans from denial, anger and depression to acceptance.

In a concerning development for the team and New Zealand Rugby, fans now appear to have moved on to a new stage: cynicism. A New Zealand newspaper dubbed the team under head coach Ian Foster "Foster's Imposters", capturing the mood of many fans which soon might even lapse into ridicule.

Foster has continued to insist his team is not far away from the level of performance fans expect. But his messaging has been mixed. On one hand Foster says the All Blacks team is going through major change which will take time to achieve, but on the other he says only minor improvements are needed to reach winning form.

Foster at times has listed inexperience among the All Blacks' problems, though two members of last weekend's starting 15 against the Pumas had played more than 100 tests and four more had played more than 50.

He has struggled to convince fans that he has a clear understanding of the causes of the team's form slump and has a remedy. Instead, he has called on fans to be patient.

"It's frustrating I'm sure for the viewers and the fans and it's frustrating for us," he said. "We have got a lot of faith that some of the things we're building are paying dividends but it needs to happen quickly. We know that.

"It seems we're taking a couple of steps forward and then one step back so that is frustrating. We are trying to build some new stuff there but we just have to keep working on that."

The fourth week of Rugby Championship action will get underway this weekend, with the All Blacks in dire need of a victory as they host Argentina in the early hours of Saturday morning.

Ian Foster's side have won just one of their opening three games in the tournament, and they will be looking to exact revenge on Argentina, who came out victorious when the sides met last weekend.

It could be a make-or-break game for Foster in the All Blacks hot seat, and you won't want to miss it.
