“We have had a good experience, we have cemented some relationships on the pitch”
Russell Martin failed to attack a cross ball as Kirm got in front to head the opener, after Charlie Mulgrew could not stop the cross following an initial challenge.
But Levein was generally pleased with the pair on their first starts after losing first-choice full-backs Alan Hutton and Phil Bardsley to injury.
"Strength in depth is important," said Levein. "We lost two really good players in the full-back area and the two boys who came in I was really pleased with.
"Charlie Mulgrew has been on top of his game with Celtic, and Russell Martin as well, I thought they were excellent."
Scotland ended the game sitting deep but more than held their own for the first hour or so. And Levein believes the trip will help in competitive games against the likes of Serbia, Macedonia and Croatia.
"This experience is invaluable to the players," he explained. "When we come away in similar situations in the World Cup qualifying campaign, it's good to recall this and remember we played a good match.
"It's a friendly match and I understand that but we have got the players together for three or four days, we have had a good experience, we have cemented some relationships on the pitch.
"I have got nothing but praise for the lads and also the supporters.
"They backed the boys and they can see some good class players and also some real promise for the future, what I consider to be really exciting talents."
