The Canaries won 1-0 to move within four points of an unlikely escape from the Premier League relegation zone.
Jamal Lewis' fine goal gave the Canaries a precious win against Leicester.
Speaking to canaries.co.uk, Norwich boss Daniel Farke said: “We wanted to show a reaction today after the Wolverhampton game when we were not on top of our game.
“To be here against Leicester playing in the best league in the world against one of the best teams in this league with a well-deserved win and a clean sheet, it's quite good. I have many compliments for my team.
“We know that we are in a good shape. All the last five games before Wolverhampton, we were on a top-class level. Even against Wolverhampton, we were good in periods but not physical enough in the duels and not switched on enough in the soft skills.
“We spoke about this a lot in the recent days and the lads delivered a perfect performance in these terms today."
After the Wolves defeat, Farke admitted his team needed to improve their work on duels and they did so at Carrow Road with a committed display.
“The most important stat was to win the duel rate today and we won this. This was the key topic in order to get this three points.
“We had several chances, especially in the second-half and even before the first goal. We showed a committed approach and were tactically disciplined and concentrated."
Farke was also delighted with the clean sheet, City's third in six matches.
“It's the 28th gameday and we've only had two games where we've had more than two centre-backs available. It says a lot about our season.
“We know that it's always tricky when you have to change crucial positions but we spoke a lot about our tactical behaviour after the last game. The lads were brilliant today.
“You can have an idea but the lads have to bring it onto the pitch. Good defending is always the basement for good results and we are heading in the right direction."
