The All Whites will face an extra Mexican player in the form of 105,000 screaming fans at the Azteca Stadium today.
While the All Whites boast a fairly experienced side, few will have played in such a cauldron. The young guns may understandably be awestruck by the occasion - how quickly they adapt to the atmosphere will have a massive bearing on the outcome.
I have no doubt the Mexican team selection was as much a psychological one as a playing one by coach Miguel Herrera, who picked only domestic players. They will have felt the passion and pressure of the build-up so will be fired up.
It's important for Mexican pride to qualify for the World Cup finals, especially against New Zealand, who are ranked 79 in the world compared with Mexico's 24. Mexico have played in 14 World Cup finals, and the qualification of unheralded Honduras and Costa Rica will have rubbed salt into the Mexican wounds. There will be huge pressure on the match officials and history shows that 50/50 decisions tend to favour the home team in such an atmosphere.
Ricki Herbert has copped some unfair criticism about the makeup of the All Whites. He has selected his nucleus from current key All Whites, taking into account injuries, retirements, etc. I don't know what else he could have done. The brutal truth is we don't have the depth of four years ago.
