Argentinians Federico Bock and Julio Brolese have already played in a World Rugby Classic final against the Springboks, so will know exactly what to expect today.

The two Pumas, whose side advanced to this year?s final with a comfortable 14-5 win over Australia on Thursday, played as injury replacements for the Aussies in last year?s tournament climax and witnessed first hand the power of the Francois Pienaar-led Springboks who romped to a 22-12 victory.

This year?s South African side, who earned their spot in the showpiece final with a comfortable win over the Lions on Wednesday, still have the power in their backs but aren?t quite the force they were last time around, even by their own admission.

But their ability to launch attacks from anywhere through Jan Harm van Wyk, Andries Fourie, Jacques Jonker and Rassie Erasmus, means the Pumas are going to have their work cut out.

They are expected to employ the same tactics the Lions attempted in the semi-final, playing keep-it-up-the-jumper rugby and keeping things contained and solid.

It failed for the Lions but the Argentinians, as they proved against the heavily-favoured French in their opening game, are a lean, aggressive fighting machine and will scrape, battle and scuffle for everything they can ? and also have a few weapons of their own.

?We are very happy to be in the final but we know it will be hard,? said the lanky, speedy Gustavo Jorge after scoring both tries in the semi-final victory.

?The South Africans are very good but we deserve something as well. I would be very happy to score two more tries, of course.?

Although the Argentinians? exact approach to the clash with the clear tournament favourites might be somewhat lost in translation, their confidence is not.

?The South Africans are very good team, they are best team in tournament,? said coach Rafael Madero just after giving out congratulatory kisses for his entire team after their win over the Aussies.

?But we can do big surprise for them.?

Argentina looked good for the final spot on Thursday, despatching the toothless Aussies with little trouble courtesy of a couple of Jorge tries, breaking from deep, in the opening 23 minutes.

Although Matt Skene pulled one back for the Aussies on the stroke of half-time, finally crossing after sustained pressure, after the break they never really looked like getting the extra scores they needed to pull back into contention.

A series of injuries rocked the Aussies, as they always seem to do here ? Damian Smith was forced to play pretty much the whole match in bloodied bandages ? although the worst injury of the night came for the Pumas, losing Fernando Conti to a broken leg in a sickening collision.

The game was held up for seven minutes ? most of which was spent waiting for the St. John?s Ambulance crew to eventually respond to requests from the PA announcers that they were needed ? but the loss of a team-mate only spurred the Argentinians on to victory.

And the South Africans go into today?s match knowing they are up against a side desperate to knock them off their pedestal ? and have known it for a year.

?As soon as you win, people start thinking about ways to beat you next time,? said Mac Massina, scorer of the final, spectacular try that hammered the nail in the Lions? coffin in the semi-final.

?Everyone is coming out firing against us, wanting to stop us winning again and we can expect that in the final too. It?s what happens when you?re the defending champs.?

South Africa?s chances of dominance depend, to a certain extent, on the weather. A dry day will allow them to toss the ball around, probably to devastating effect, while rain will slow them down and force them to try and match the Argentinians up front, which they may not be so successful at.

In other matches, the day begins with a Bermuda Select taking on the Canadians, who ?won? the right to play the host nation by losing their two matches here so far this week.

The Canadians are expected to be too strong for the local team, although age will be very much on the side of Pete Shillingford?s men as will the support of thousands of partisan fans.

In the second match of the day, France take on Team America in the plate final, and then at 6.30p.m. the Lionesses meet the Golden Eagles in a women?s international before the tournament?s 8 p.m. climax.
