What millions?
NZF is broke as it is. Any money made from the Mexico tie will certainly not go towards a "quality overseas coach".
Not gonna happen.
Also I've read a figure of $5 million from selling the second leg television rights and ticket sales. Reportedly there's still about $4.5 million of the WC 2010 money invested. That's hardly "broke".
The problem with bringing in a good overseas coach, and I'd love a fresh attacking mindset, is a lack of games. NZF hardly likes to dip into it's purse to fund internationals. However a new coach could target the next Confederations Cup in 2016, which should, if we qualify, be self-funding from the $1 million plus prize money for winning Oceania. That should be a decent carrot for any up and coming coach wanting to make a name on the international stage. Outside of Ramon Tribulietx of ACFC, I don't think there's a domestic coach good enough.
