Nottingham Forest manager Mark Warburton said The Reds paid the price for the two goals they conceded on the stroke of half time in the defeat against Bristol City.
A spirited second-half showing from Forest wasn't enough as they gave themselves 'a mountain to climb' in the final 45 minutes.
Speaking after the game, Warburton said: "We paid the price for a sloppy first half. I think in the first half an hour we weathered the storm which you expect when you go away from home. We were at 30-35 minutes at 0-0 and we have conceded some soft early goals so we were thinking that we were in the game and can play.
"The first half was frustrating as, even though we weren't playing very well, to get to 35 minutes at 0-0 gave us a chance to get to half-time, regroup and go hard again in the second half. But we went in two down and gave ourselves a mountain to climb which was the biggest frustration for us.
"The first goal is a soft goal to give away. The second one, the lads have said it swerved beyond belief and that Jordan went one way, the ball the other. We were 2-0 down and you come in and say to them that we didn't create chances, didn't look after the football well enough and they were the better team.
"In the second half you saw a seven out of ten performance and we completely dominated the second half. Kieran got a great goal, missed a tremendous chance across the face of goal and we looked the better team but we can't wait until half time to do that.
"I thought they were tiring, we had an energy about us and we were picking up the second ball. It was completely different to the first half and I thought the chances would come; it came across the face of goal and those are the fine margins. If we took that with ten minutes to play, then we would have been in good shape."
