Hooker confident of Argentina success
Ross Ford believes Scotland's past form against Argentina will stand them in good stead ahead of their Pool B encounter.
Scotland were knocked out by the Pumas in the quarter-finals in 2007 but Andy Robinson's men recorded a 2-0 series win in Argentina last year.
And Ford insists Scotland can be confident of success in Wellington on Sunday following those victories in Tucuman and Mar del Plata.
Ford said: "We've played them a lot of times over the last four years - we're well rehearsed in what they're about, as are they.
Potential
"We won the last two Tests and that's a good boost for us knowing we can go away from home and play like that.
"It's really about turning up on the day and playing to your potential. We know we have to turn up ready to win."
Scotland can book their place in a seventh successive quarter-final with victory over Argentina, with Ford aware of the importance of match.
The Edinburgh hooker added: "It's definitely up there. A World Cup game is pretty special, but this one is especially - it's definitely in the top 10 (of my career) I would say.
"It's an important game for us and I'm looking forward to it.
"We've had a long time to prepare for it - it's been a long turnaround from the Georgia game (on September 14) to this game - so we've had time to think about it and time to put in some good training."
