Huddersfield manager Mark Robins admits he feels side have taken one step and forward and then two back following their 1-0 defeat at home to Charlton.
Callum Harriott's early strike was enough to earn the visitors their eighth away win of the season at the John Smith's Stadium, to take them up to 12th while Huddersfield are just five points above the drop zone.
Town were on a high following their midweek win over Middlesbrough, when two late goals earned them a 2-1 win, but for Robins the result was a real kick in the teeth.
"What a difference a couple of days make," he said. "We were brilliant on Tuesday but we have been undone by a set-play.
"It feels like a step forward then two back but we have to take these on the chin I am afraid.
"We've not had enough quality. We have had plenty of ball in their box and although the way we got it there wasn't ideal, needs must at times."
Only Cardiff and Watford have won more games away from home in the npower Championship this season than Charlton and manager Chris Powell was keen to praise his back line, which recorded its first clean sheet in 17 games.
"It was hard-earned but I'm really pleased with the performance of the players," he said.
"We had the perfect start. We countered well, we knew we would have to be on our mettle in the second half and we knew the pressure would come.
"Every player played their part but the centre-backs and the goalkeeper, they showed a real desire to keep the ball out of the net. It has been a long time coming, the clean sheet, I'm really pleased for all of them."
