Scotland coach Andy Robinson admitted his side had been lucky to beat Samoa in a dramatic finale.
Rob Harley, making his Test debut, came off the bench before scoring the try that put his side in a position to win the game with Greig Laidlaw's conversion sealing a 17-16 triumph .
Despite winning all three matches on their summer tour, the first Scotland squad to achieve that feat, Robinson was keeping his feet firmly on the ground and believes his side had struggled to hang onto the ball and that failure could have cost them the result. He said: "For a lot of that game, they looked the better side."
He added: "They kept hold of the ball better than us.
"Defensively we were very good in the first half but we dropped off one tackle and that led to a score.
"Sometimes you have got to find something and I think that when Mike Blair charged down a kick just before the try, that showed the energy that there was among the team, they weren't prepared to give up.
"Winning is a positive. We kept fighting but we want to be able to play against the very best, compete against the very best and beat the very best.
"I thought that there was more to come from us, I thought there was more skill.
"We didn't do that today, we couldn't string together one phase, but when we did, we scored seven points."
