The All Whites will always struggle for depth and an injury to a key player will be keenly felt, as Winston Reid's absence was tonight.
Tonight's result was predictable given the makeshift nature of the team fielded by Ricki Herbert, who gave debuts to two players and lined them up in a 4-4-2 formation he hadn't used for years.
The good news is there are no end of areas where the All Whites can improve. Being better organised at set pieces would be a good start. New Zealand gave up two goals from corners at the Azteca and struggled to contain Mexico again last night from dead ball situations.
Part of that simply comes down to time spent together. There needs to be a greater commitment from New Zealand Football to provide a better build-up campaign and from the offshore players to make themselves available at every opportunity. It remains to be seen whether the former has the cash and the latter the desire.
This was the youngest team New Zealand has fielded in many years. Some may turn out not to be good enough for international level but there were some encouraging displays, none more so than Bill Tuiloma in his first start.
The 18-year-old fullback was wearing Ryan Nelsen's No 6 jersey and some of his play was a little reminiscent of the former skipper. At one point, he made a covering tackle in the middle, won the ball and then pointed Nelsen-style to where Kosta Barbarouses should be playing it.
He called for the ball with confidence, made overlapping runs and had a first-half shot from distance when players in front of him seemed unwilling to have a go.
In charge of the All Whites for the last time, Herbert was afforded generous applause after the final whistle. He oversaw a period in which much of the general sporting public came to care enough to get angry about football in a way they didn't before, even if there remains a level of ignorance about how tough it is to excel in football from those who follow non-global sports such as rugby.
Contrast that with the lack of an outcry after the 4-2 loss to Vanuatu which effectively ended New Zealand's 2006 World Cup campaign.
From a personal standpoint, Herbert's biggest mistake was perhaps not signing a lucrative contract with a Middle Eastern club when his stock was at its highest after the 2010 World Cup. But Herbert demonstrated the kind of loyalty that has all but disappeared from football by staying with the All Whites and Phoenix. One wonders if the leading offshore All Whites will show similar loyalty to their national team in the next World Cup cycle, especially if New Zealand draws a much tougher qualifying path through South America.
