Daniel Farke admitted City were second best as they were beaten 2-1 by Sheffield United at Carrow Road.
Ivo Pinto’s brilliant header gave Norwich hope with 20 minutes remaining, but the Blades hung on to win 2-1.
“I’m pretty disappointed with the result,” Farke said. “We knew it would be a tough game after Chelsea but we wanted at least to get a draw to continue our unbeaten run, so we’re sad about this result.
“I think we were tired in the head today, and we made some mistakes in our pressing and in our decision-making. We know if we’d won we’d be back in the playoff mix, and you go in so motivated. But we have to accept the loss.”
Farke was pleased with the way Norwich responded after a poor opening 30 minutes, but was disappointed with the two goals his side conceded.
“Today after five minutes we gave away an unnecessary corner kick, and then the tiredness comes in a bit and we were really struggling in the first 30 minutes. But the last 15 minutes of the first-half we put pressure on them and I got the feeling in the second half that we could go on and turn the game.
“But then a simple mistake leads to 2-0 and to be honest after that it’s really hard to turn the game against a good squad after the week we’ve had. We tried everything and took a lot of risks after Ivo’s goal but it wasn’t enough.
“I was content with our response because we tried to fight our way back into the game. But Sheffield United defended really well.”
Farke admits he is hoping for some fresh faces to add to a thin squad over the next couple of weeks, with Brentford up next on Saturday.
“We are a bit thin in the squad offensively but it is what it is, and I try to bring the best out of them in this game,” he said. “So I don’t complain about the situation, but I hope we can strengthen the squad in the next days, especially in the offence.
“We’ve sold some players and have created space, so we have the opportunity to bring some new lads in so I’m confident we can bring in two or three new players.”
