Scotland face Argentina today with victory as their only goal in Buenos Aires as they bid to end the summer tour on level terms.
The Scots came close to winning last Saturday in Rosario, but after leading 15-10 they ended up losing 21-15 after the Pumas exploited their problems at the breakdown.
Boss Frank Hadden and the 30-man squad worked during the week to prevent that from happening again as they bid to secure their first triumph against the world’s third-ranked side for 18 years.
Hadden has made several changes to the starting XV, with Phil Godman replacing Dan Parks at fly-half and openside flanker John Barclay brought in to provide balance to the defence.
Chris Paterson moves from full-back to the right wing with Hugo Southwell taking the sweeper role and Simon Webster on the left wing.
“We are here with a lot of pressure to win this match having missed a good opportunity last weekend,” said Hadden.
“I am delighted with the way we trained this week, we have gained significant confidence from that.”
Paterson, who last week surpassed Gavin Hastings as the country's all-time leading points scorer and equalled Scott Murray's record of 87 caps, expects to be able to celebrate his record with victory this weekend.
“It will be a close game,” Paterson said. “The World Cup one was close and also last weekend. The teams are quite similar in many ways.
“I will be closer to the action and getting my hands on the ball more often. I will have more chances to attack, but the only important thing is to have a good performance for the team. I hope this could be a special match so I can celebrate my records.”
Paterson added that a tougher physical approach and nullifying the pace of their hosts will be crucial.
“Argentina dominated the contact areas (last match) and we have targeted solving that this week,” he said.
“The speed of the ball will be important in order to increase the attack. Our defence was quite good, but we could be more dominant and making more tackles.”
Godman feels taking the initiative is the only way to cause real problems for the Pumas.
“Argentina’s backs are outstanding so we will have to look to quickly put the ball up because we need to attack a bit flatter to commit the Argentinian defenders more,” he said.
“We need to have the pace of the match. I am sure that it will be a tight game again.”
Godman added being alert to the movement of Pumas centre Felipe Contepomi will also prevent the hosts playing to their potential.
“Felipe Contepomi, he is always very dangerous. He is a class act,” admitted Godman.
“He is more than a centre he is also a playmaker so we have to watch him. Argentina’s back three are also very good and also the number seven (Juan Fernandez Lobbe).”
