Glenn Roeder backed David Marshall to become Scotland's number one after Norwich's victory over Nottingham Forest.
Marshall produced a string of excellent saves as the Canaries held on to win 2-1 at the City Ground despite being reduced to ten men after just 20 minutes.
The goalkeeper kept out a powerful free-kick from Matt Thornhill and twice denied Joe Garner with flying stops.
"We have a keeper who could become Scotland's number one keeper," claimed Roeder.
"I want him in the coming months to believe in himself as much as I believe in him and we believe in him.
"I am not sure which was his best save but I am told it was the one from the free-kick. He was electric to get down to that in the corner."
A Matt Pattison strike and Chris Cohen own goal sealed Norwich's success and Roeder was delighted with the attitude of his players.
He said: "I accused them - not as individuals, as a team - after a couple of average performances of lacking some courage away from home. And they threw it back in my face."
Forest boss Colin Calderwood was left fuming by his side's second-half performance, which left them at the foot of the table.
He said: "It was a horrible second half. We under-performed. The game was there for the taking - a real missed opportunity to maximise our game and get the three points.
"We didn't play in the second half and it overshadowed a really good first-half performance.
"(We showed) poor execution on individual things, and there was no real danger against their back four.
"We really failed in the second half. That's cost us and put us in a black mood."
