Larsson admits the players had to face up to some uncomfortable facts.
The Swedish international said: "We had a very good, honest chat afterwards and I think the bottom line was we did not show we wanted it enough.
"Whatever is said in the dressing room stays there, but we had a good honest chat and that is what you need from time to time.
"It sounds bad, but I think Norwich wanted it more than us.
"It came down to desire.
"At this stage of the season, if you do not have the desire to do what is needed to pick up points, you are going to struggle. "Let's find that desire very, very quickly.
"I do not know why that was. I would like to have the answer."
