Head coach David Wagner spoke to Canaries TV following the club's 3-1 defeat against Blackburn Rovers at Carrow Road.
Norwich found themselves 2-0 down early on and Wagner says they never recovered from the early concessions.
"In the first minutes, we came into the game quite well. We had some good turnovers high up and didn't execute the opportunities," he said.
"Afterwards, when we didn't get our press right, we got punished and were 2-0 down. They've done it better, we had high turnovers without clear-cut chances out of those situations. "
"The second half started very poorly with the goal we conceded, another from a transition after a set-piece which we had. We have to solve this issue much better, take responsibility and be switched on which we were not."
However, the head coach praised the effort of the squad and their willingness to fight to the end of the fixture despite being three behind.
Numerours chances arrived but without success until injury time when Gabriel Sara scored a consolation.
"I can't complain about the effort, again the players tried until the final seconds. They really wanted to change things but obviously it was not good enough because it's a defeat. I'm the manager and I have to take responsibility for it," Wagner added.
"The players tried. We were not clinical today, we created enough opportunities to score more than only one goal. It's a horrible run that we are on, it hurts for everyone.
"After the red card and the substitutions, we attacked quite well, we made opportunities. Apart from the last 10 minutes, we played an overload well without being clinical in those situations, we had to score earlier to get more belief, more energy. The longer it took, the more difficult."
