Millwall manager Neil Harris was understandably unhappy with The Lions' 1-0 Sky Bet Championship defeat to Burton Albion at The Den on Saturday afternoon, citing "a lack of responsibility" from his players.
Marvin Sordell's 70th-minute strike handed The Brewers all three points in a game that also saw Millwall reduced to 10-men following Jed Wallace's red card.
The boss bemoaned a lack of finishing from his forwards in the loss, as well as stating how Wallace's dismissal "changed the game."
"We should be more clinical," he said. "The forwards with their chances wasn't good enough and the attacking play wasn't good enough.
"We've been in every game this season, including today. People have to take responsibility. We should've been in front today and in previous games, we should've been out of sight.
"I'm unhappy with the result and whilst there was no lack of effort from my players, I don't think they were brave enough in their decision making with 11 or 10 men.
"The first goal was also going to be vital today and after we didn't get it, plus the red card, that gave us a mountain to climb. I'm disappointed with the quality in the group and that we haven't scored a goal at home. My frustration is borne out of my players letting themselves down.
"Today's sending off is a pivotal one, because we're at 0-0, at home, in a game we're completely on top of and never look like conceding a goal or losing the game - and that changed the game.
"I've spoken to my players and they're in no uncertain terms of where I'm coming from."
Shane Ferguson missed the match through illness, and Harris confirmed that the winger was suffering all week, especially after Tuesday's night defeat to Sheffield Wednesday.
"Shane was struggling after the game the other night and he has been ill this week, so he couldn't be involved."
