Millwall boss Neil Harris claimed that whilst Tuesday's 1-0 Emirates FA Cup Fourth Round Replay defeat to Rochdale was a "disappointment" and a "setback", it wouldn't detract from The Lions' Sky Bet Championship campaign.
Ian Henderson's 54th-minute strike sent Dale through to a Round Five meeting with Tottenham Hotspur or Newport County on a bitterly cold night in Lancashire.
The game was also played on a sandy surface - with Harris stating his players "didn't get used" to the pitch.
"Firstly, congratulations to Rochdale. They played the conditions much better than us tonight. My players didn't really get used to the pitch," he said.
"I have no complaints with the result whatsoever. With regards to my time in charge, that's a bit of a low, but I'm not going to let that derail how well we're doing this season at the moment.
"Other than a couple of defensive blocks and goalmouth scrambles, there were no chances in the game bar their goal. At half-time, I said there would be one mistake, one moment of quality or one hero that would win the game, and they obviously produced that."
The manager quickly turned his attentions to the bread and butter of the Sky Bet Championship and Friday night's televised visit of Cardiff City.
"It's a disappointment, it's a setback, but we now move on to Friday. We've let ourselves down a little bit over these two games and it would've been nice to have played Spurs or Newport, but we move on to Cardiff.
"We now make sure the players get the right recovery with the quick turnaround. My players are disappointed - they know they haven't performed. Sometimes you just have to say well done to the opposition."
