Scotland manager Gordon Strachan has praised the way his side have performed in training over the last couple of days.
The Scots drew 0-0 with the USA on Friday in the first of two international friendlies, with the second coming away to Norway tomorrow night.
Strachan will be forced into a number of changes for the match having seen Steven Fletcher, Charlie Mulgrew, Grant Hanley, Ross McCormack and Matt Gilks all pull out of his original squad, but the 56-year-old has been delighted with the way that his players have adapted in training.
"The players' performances the last two days have been absolutely fantastic. I congratulated them yesterday on how well they did at training, it was excellent," Strachan told PA.
"We have been working on something a wee bit different. There will be change in personnel as well as a small change in what we are going to try. We have looked at something to bring a wee bit freshness to it.
"So we have used our time, we think, wisely again and there was a tremendous performance by the players. We worked on a certain ways of doing things and that was good, it was great for the coaches, it made us feel good about ourselves."
Scotland have only beaten Norway three times in 17 matches and were on the receiving end of a 4-0 drubbing last time the two sides met.
