The side from Old Trafford are through to the final eight of the Capital One Cup after an impressive performance which saw them poach four goals against the visiting side from Carrow Road.
While goals flowed from Javier Hernandez, Phil Jones and Fabio, United’s keeper, who kept a clean sheet during the game, was more impressed with Januzaj's spirit and tenacity during the night.
"I think it's lovely to see how great Adnan is doing," said Lindegaard.
"He gives hope to the whole United spirit, a young lad coming through from the academy into the first team. He's doing absolutely fantastic. You see what an impact he's had, not just tonight [Wednesday] but on other nights as well.
"Adnan is cheeky both on the pitch and off the pitch. He seems very balanced in his personality and that's great to see from an 18 year-old kid. He plays like he's played 200 Premier League games already. I'm just very impressed with him."
United seem to be bouncing back from a poor start to the season, and this latest display at Old Trafford has Lindegaard and team believing that their luck might be changing and goals will start to flow their way.
Assistant manager Steve Round was especially pleased with the result, and Januzaj’s performance.
"It was a terrific result," Round excitedly told press in a post-match interview.
"I’m really pleased. To score four at Old Trafford is always special and it’s great to for some of the younger players to be able to experience a game at this level against a good Norwich team.
"I was really pleased for Wilf Zaha to get a start and play so well tonight [Wednesday], a couple of the other younger lads also did well such as Tom Cleverley and, of course, Adnan, who’s getting stronger by the game.
When asked if the side from Old Trafford had a different strategy coming into the League Cup, Lindegaard replied that their approach was no different and the goal would always be a victory for United.
"I don't feel any different about this competition to how I feel about the Premier League or the Champions League. The approach is the same. It's the United way to try to win all the competitions we participate in and every game we play in."
