Daniel Farke admitted Norwich City’s 2-1 defeat to Sheffield United was “difficult to take”.
The Canaries controlled the first-half and led at the interval thanks to Alex Tettey’s thunderous strike but the visitors responded early in the second-half to lead by the hour mark.
City never recovered and succumbed to their second straight defeat.
Speaking after the final whistle, Farke said: “It’s a difficult one, a suckerpunch. We are disappointed because we had a great chance to be back in the mix with a win and improve our situation.
“We played a really good first-half and were in the lead. We had the chances to be one or two more goals up in order to decide the game.
“The mistakes we had before we conceded the goals in the second-half for the 1-1 and 2-1, of course that was disappointing.
“It was a shock and you could feel it on the pitch. We were struggling in this period and in the last 15-20 minutes, we tried everything in order to turn the game.
“The goalkeeper was there with one or two decent saves but in general, we are unbelievably disappointed that we were not able to play a better second-half."
Farke bemoaned that five-minute spell which ultimately cost City the game. He also said it was difficult for his young side to recover.
“Small details always make a huge difference at this level. I was so disappointed with the 1-1 because it wasn’t even a chance for them. It was a throw-in and we spoke so much in our preparation for this game about them using their throw-in situations to create crossing situations.
“We knew exactly how to defend this, but we didn’t do this. We also spoke about from wide positions they bring their wing backs and centre-halves in, in order to attack the crosses.
“In this scene, at least we had to jump or disturb but we were not switched on in this scene.
“The second goal was also not a situation where the ball should end up in the net. We had the first touch in our box and gave the ball away. Their wing back has his back to our goal out of a difficult angle and somehow scored.
“When you concede two goals out of these situations, they were totally on the up. It was a unbelievable shock, especially for our young side.”
