Nottingham Forest manager Martin O'Neill was left disappointed as three quickfire goals at the start of the second half saw The Reds fall to defeat against Sheffield Wednesday.
O'Neill felt the first-half display was positive but missed chances and cheap goals conceded ultimately cost his side.
Speaking after the game, he said: "We are really disappointed. In the first half we were excellent and could have scored a couple of goals, but it always comes back to haunt you.
"There was a mad spell at the start of the second half when we conceded a goal from our own throw, the second from our own set piece and it was disappointing.
"Unfortunately, we showed a brittle side of us again and we lost, maybe it was a bit harsh but we have been beaten by three goals when it could have been so different.
"We have broken on them on a number of occasions and I thought we played some delightful football. We had played coming in, Arvin doing his best and Sam Byram coming in and doing fine.
"We have got these chances that we have spurned and we can't keep doing that. I don't care what league you are in, you can't spurn these chances. Of course, when we don't get the first goal then the confidence saps."
