Boss upset after loss in WalesManager Nigel Adkins was left to rue the concession of two goals that cost his team any chance of a result at Cardiff.
Two goals in the first half, as well as a red card for Alex Pearce, saw us ultimately beaten 2-1. Michael Hector got a goal back late on, and we may have got something from the game but the two-goal deficit was too big a mountain to climb.
He said, "We came away against a team who are in good nick at home, we quietened the crowd in the first 20 minutes, but then conceded the softest goal going.
"It was a corner put in there, unfortunately one of our players has his body position all wrong and deflects it into the net. So having started well we're 1-0 down.
"Then the game is toing and froing, we had I think 60% possession in the first half but have conceded an awful goal on half time. It's a simple ball over the top that we have to defend better. It's a penalty, but for me it's not a red card. His angle is going away from goal, we've got a covering defender and Federici is about to pounce on it.
"So it's changed the complexion of the game and at half time we're a man down. Then we have to manage the game, we went to a 4-4-1 formation, we knew the next goal would be important, we had width in McCleary and Robson-Kanu. Then in the last 15 minutes we put two up there to penetrate, scored a goal and could have had another.
"So unfortunately the goals we conceded in the first half have been our undoing."
He continued, "We've conceded too many goals away from home and I won't hide away from that fact. It's no good me saying how hard the lads are working, because it's about results and I won't shy away from that.
"To be fair to Pearcey, he has done great to play for Ireland on Tuesday night, maybe I could have played Coops tonight. I have to make sure we keep everyone positive and important, that's the important thing. We should have won the Charlton game, but I won't go on about should this and should that - I have to keep moving forward and I will."
