Cape Town - Springbok coach Heyneke Meyer says his side by no means underestimated Argentina in their Rugby Championship Test in Mendoza on Saturday.As it happened: Argentina v SAThe Boks were somewhat lucky to escape with a 22-17 win after trailing for most of the match. This performance was a far cry from their 73-13 demolition of the Pumas the previous week in Soweto.But Meyer insists they did not take their opponents lightly, and believes had they done so they would have lost the match."We knew they were going to come hard at us. And then when they scored that first try (in the second minute), we were immediately under pressure. If we underestimated this team, then we wouldn't have won," Meyer told the Beeld website."But we were by no means lucky with this game. It (the performance) wasn't good enough, and if you were in the change room afterwards you would have seen that the guys aren't happy. And if you win by five points and you're not happy, then it's a sign of a team on the up."Bok skipper Jean de Villiers said the positive out of the game was that they improved from last year - when a similar performance saw the Boks draw 16-all in Mendoza."Everything we wanted to do - the things we paid attention to during the week - we didn't do well at all. It was very much the same as last year, but on a positive note we've come really far since last year to now win this match."South Africa's next Test in the competition is against Australia in Sydney on September 7.
