Dagenham boss John Still blasted his side's defending in their 3-1 defeat to Southend in the Johnstone's Paint Trophy.
Ryan Hall netted twice and Neil Harris also scored for the Shrimps with Damien McCrory getting on the scoresheet for Daggers.
Still said: "They're going well at the moment and obviously are quite decent, but we had some decent performers, particularly the goalkeeper.
"I was very disappointed with the first goal. Phil Walsh switched off a little bit and they got in behind him, so that was very disappointing.
"We said at half-time, forget how you play, but you've got to concentrate.
"This being a cup game, I have to put this in context to the league form. We could be flying in the league or struggling in the league, this is different, we put people in that we felt needed the game."
