NEIL Harris slammed Millwall's shambolic defending after their FA Cup defeat to Southend United – a team 31 places below them in the league pyramid.
The Lions, already a goal behind, were reduced to ten men when Jermaine Easter's stamp on Ben Coker resulted in a straight red card.
But Harris says the sending off was no excuse for the overall performance.
"The players let themselves down," the caretaker boss said. "It wasn't good enough. The goals were a shambles.
"Jermaine has let himself and his team-mates down. We were second best all over the pitch.
"You cannot give any team four goals. We have defended like that all season, we've let in over 50 goals, which is no surprise when you play like that.
"We felt at 2-0 down at half time with ten men, we couldn't chase the game straight away. We hoped we would get a set piece or a bit of magic from someone, and we were about two switch to two upfront when Southend scored their third goal.
"Wooly scored a fantastic goal, it was a bit of magic, and he did really well when he came on. That gave us hope again, and we went to two upfront, and we had chances. We don't score, and then give a poor fourth goal away.
"We didn't compete in the first half and hour, and the game was lost in that period. You can see how disappointed how I am.
"The players didn't compete. They were given an opportunity today and just didn't take it."
