Daniel Farke outlined uncharacteristic mistakes as the causes of Norwich City's 2-0 defeat at Swansea City on Friday night.
"We're disappointed we lost this game," he said. "It was the spotlight game on this level between two really good Championship sides - a home game for Swansea against us with our third game in six days - so everything has to work to get away with a result.
"It was a tight game and we were a bit on the front foot in the first half and pretty close to making things happen with a good through pass of Cantwell to Pukki, but Swansea are always dangerous out of counter-attacks.
"I got the feeling we controlled their counters but sometimes they have a set-piece and on this level you have to make sure that you are not there with the first mistake. Football is often a game of mistakes and we made the first big one before the first goal.
"When you offer something a player like Ayew has the quality to punish you. The second half was more or less the same.
"For the goal, we unnecessarily gave the ball away and were then quite open. Hourihane, with his quality, was able to punish us with a strike out of 30 yards.
"When you're then playing against the best defending side in the league and they can concentrate on defending 2-0 up, we tried everything and changed the formation two or three times and brought many offensive players on the pitch.
"The lads showed great mentality to go until the end. There was no disappointment on the pitch and although it's difficult to turn this game, they kept trying. We didn't find the solutions in the box to score a goal.
"There were a few penalty incidents but the referee wasn't willing to give something.
"I wasn't pleased with the mistakes today and they were the reasons we lost the game.
"Congratulations to Swansea and we have to accept this because on this level when you make the first mistake you will lose such a tight game.
"In the first game against them, they made a small mistake and Marco Stiepermann punished them and that's why we won that game. Today it was our mistakes and Ayew and Hourihane punished us."
Farke was keen to put perspective on his side's current situation, discussing his enthusiasm surrounding the substitutes as well as those who could return in upcoming weeks.
"In the period they scored in the first half, we were more and more dominant. To get this setback was difficult and you speak about how to improve and create a bit more, then you get such a sucker punch.
"We were a bit overexcited and Hourihane is a top class striker of a football. It was difficult to stay with the belief but I thought the substitutions did really good so I was pleased with them.
"Previous times, I've felt that substitutes weren't quite ready so today was a step closer for Onel, Kieran and Idah, so good for them to have a normal training week now as well. They need that to be an option for the first-team.
"Emi is available for the next game and hopefully Jordan and Marco will return soon because we need all our options back.
"I will allow them to feel disappointed because you need to feel this in order to be greedy to be spot on and fully focused in the next game.
"The longer the game went on, the more we'd have had chances to win the game if it was 0-0 as they'd have needed to open the game because the pressure was on them.
"The players know themselves they shouldn't make these mistakes in front of goal."
