I'm an American living in Wellington, really looking forward to seeing Mexico here.
I generally root for CONCACAF teams in all circumstances where they aren't playing the US, but i'll definitely be pulling for the All Whites in this one.
But, while i agree that Mexico is ripe for the picking, i just don't like the idea of NZ going into Azteca.
Sure, there have been some 0-0 draws there this round of qualifying, but there is a bit of a difference (to put it mildly) between the battle-hardened CONCACAF squads who have went in there and gotten a result and this current NZ side.
Though, of course, anything can happen on the day...
