George Burley has insisted that his tactics could not be faulted following the goalless draw with Norway.
The Scotland boss opted to go with James McFadden as a lone striker in Saturday's crucial World Cup qualifier.
The inexperienced duo of Steven Fletcher and Chris Iwelumo were then brought on as substitutes in the second half ahead of Kris Boyd.
Burley's decision to introduce Iwelumo backfired when the debutant missed an open goal but he does not believe he should be criticised.
He said: "Tactically, you look at it and assess it and I think I got it right.
"With anything, if you don't change it and don't go for it then people can say your system didn't work.
"Norway made it hard for us but when we changed it we got it right in as much as we completely dominated them, and that was the time to win the game. Unfortunately we didn't.
"But we had that opportunity in the second half and if we had scored we would have won the game.
"Changing it the way we did certainly worked. The players played the kind of football I want them to play in the second half."
Burley also explained why he had placed his trust in Iwelumo and Fletcher, who had just one cap between them ahead of the game.
"I felt that big Chris would give them problems in the air," he said.
"Chris himself is six foot four and he needed a lot of movement round him, and I know Steven Fletcher's got that.
"He's a very talented player, very clever and I thought that combination would be right. When they did come on they worked very well together.
"Steven went deeper and big Chris is a target man. They played off each other very well.
"I wanted the balance. We needed the balance and those two gave us the balance. They did very well against decent players."
