I played there in 1994 with New Zealand A and I can say for a pretty naive wide-eyed boy from Matuaura on one of his first trips overseas, it was one heck of an experience. The Argentines are very passionate people, and that's just the supporters.
We lost the game, but one of the best experiences I've had at a sporting event was going to a football match featuring Diego Maradona's former club Boca Juniors. I've never been to anything like it since. Maybe 30 per cent of the crowd watched the game and the rest had a party. The atmosphere and singing was out of this world.
I've played for the All Blacks at home and all over the world, and while we were aware of the support it didn't drive us. The Argentines' culture is all about emotion and for me that makes for a fascinating challenge this Sunday. A lot of the Chiefs players wouldn't have been to Argentina before, and the stadium is likely to be packed.
If the Jaguares keep a winning record at home they should make the playoffs. They are playing a similar game plan to what the Pumas played at the World Cup. It's very All Black like with hooker Agustin Creevy popping up in the outside channels and backs forwards combining. It gives them a real balance. They can scrum and maul you to death but they're also a handful out wide.
They're big and powerful men and the Chiefs will have their hands full on Sunday.
