Robinson's men secured an historic win over Australia on Saturday but the former Edinburgh boss has decided to 'freshen' things up against the Pumas.

Edinburgh openside Alan MacDonald is set to make his international debut having impressed for the 'A' team in their comfortable win over Tonga on Friday, while club-mate Ben Cairns comes in at outside centre as Alex Grove moves to the No12 shirt.

Glasgow wing Thom Evans is the other alteration to the side that ended a 27-year losing sequence against the Wallabies, with Ulster's Simon Danielli the man dropping out.

Scotland captain Chris Cusiter has been passed fit to start at Murrayfield after recovering from a heavy knock that forced him to leave the field early in the first half last weekend.

But co-captain Mike Blair is still unavailable having had to withdraw from the match against the Australians due to an ankle injury.

"This selection is about the management of our squad and giving players that performed in the A team an opportunity to deliver a win for Scotland," said Robinson, who is hoping to lead Scotland to their first clean sweep of autumn internationals since 2002.

"I thought it was right to just make a couple of subtle changes and I think that really helped the team moving forward.

"We do have competition for places and last weekend was about two international victories at Murrayfield against Australia and at Netherdale against Tonga.

"I saw this as an opportunity to give Alan MacDonald a start. One, because he's been playing well for the 'A' team, but also because of how John (Barclay) has performed - he has done well - and the punishment that he has taken.

"In the back line, I just wanted to freshen it up a little bit with a bit of pace. Thom Evans brings that - he's the quickest player in the team.

"Ben Cairns has been playing well at 13, and potentially would have started (against Fiji) if he'd have been fit. He's got his fitness back, played in the A team game and did well.

"Alex (Grove) has been the stand-out performer in the back line and he's really held the back line together with his defence, so we're looking at him playing at 12.

"We've got to make sure that we enjoy playing with the ball in hand this week, as opposed to giving it straight back to the Argentines."
