David Wagner says his Norwich City side suffered defeat to Swansea City because they weren't clinical enough.
An 83rd-minute goal from Bashir Humphreys was the difference between the sides after Jamal Lowe and Gabriel Sara had earlier swapped efforts.
"From my point of view, first half we were not good. We didn't start well but we scored the equaliser with a nice build up and play out from the back," Wagner said.
"Second half, I think we were better, we had enough chances to kill the game. In both boxes today, we were not focused enough, not clinical enough, we had enough chances to win this. That's why I'm disappointed and angry."
The Canaries' head coach outlined how his feelings about the performance and result were echoed by the dressing room.
While he didn't fault the effort of his team, he felt that aspects of the performance were not at the standard that they have come to expect from themselves.
"The dressing room is disappointed, the dressing room is angry. It's anything but satisfied by what happened because this is a performance where I can say that for the effort and for the attitude, I have no complaints.
"They really tried, they worked hard but you have to be clinical and use your chances, goals change games. We haven't done that and defensively, the two goals we gave away and two further clear cut chances they had, it was just too easy. We have to defend more proper and use our chances as well."
It's now a fourth defeat on the road for Norwich in all competitions but Wagner says he hasn't cause for concern yet.
"The defeats we have conceded were all because of different reasons. Before that, we had a period where we were quite strong away from home. That's not what counts now, what counts is for us to make it better."
