Scotland captain and back-row forward Kelly Brown is adamant that victory can again be achieved against South Africa at Murrayfield on Saturday.
Brown moves to flanker in place of the injured Ross Rennie this week, with David Denton coming in at eight as one of two changes made.
And he believes a repeat of Scotland's shock 21-17 victory the last time the teams met in the corresponding fixture in 2010 is on the cards.
"There's no doubt it's possible," said Brown.
"We know what happened two years ago but in saying that, so do South Africa.
"So they will be looking for a bit of payback and it's up to us to make sure we really nail the level of performance that we need to to be successful.
"It was a great win, on that day I think it was based on a really solid defensive effort. We will need to make sure that we are really tight in that aspect of the game and make them work for anything that they get, and when we're on the attack we need to ask them questions and put them under pressure.
"There is no doubt there is improvement to be made. We have looked at the video and we know the areas that we need to work on. We have been doing that in training and I'm very confident we can put it right on Saturday."
