Chris Hughton hailed the performance of Mark Bunn as the Norwich stand-in goalkeeper saved a late penalty to help defeat Tottenham and set up a Capital One Cup grudge match with Paul Lambert's Aston Villa.
Bunn, making just his second start of the season, pulled off a number of crucial saves throughout the shock 2-1 win, but he saved his most important one for two minutes from time.
Having over-turned a one-goal deficit, Norwich stood on the brink of last eight, but their victory was put in doubt two minutes from time when Kyle Walker went down under the challenge of Marc Tierney and referee Jon Moss pointed to the spot.
Bunn dived low to his left to deny Clint Dempsey from 12 yards, however, and ensure Norwich's passage to the last eight for the first time in 17 years.
"I thought he was excellent," Norwich boss Hughton said. "He is a really good goalkeeper. I can't imagine he was at fault with Tottenham's goal because it was a wonderful strike from Gareth Bale.
"Overall he showed good composure and he had good hands. The save for the penalty was fantastic. He was brave."
