IAN Holloway said he was "surprised" by the lack of belief shown by Millwall's players against Ipswich Town on Saturday.
The Lions lost 2-0 at Portman Road and rarely threatened after David McGoldrick broke the deadlock 60 seconds before half time.
Holloway felt his side lost their "energy, belief and coordination" in the second period, when Daryl Murphy doubled the host's advantage.
Millwall had been the better team and created the better chances prior to falling behind, so Holloway was frustrated by their lack of a response.
He said: "It didn't look like our team in the second half.
"When a goal goes in it's like getting shot and it looked like a fatal wound. I'm surprised at that because we need people to stand up, get going and have some confidence.
"Maybe the break didn't help us but ever since I've been here we've grown in self-belief. Even if you do get beat, you never show that and you keep going.
"Today we didn't do that.
"It all broke down for us too easily in the second half – their shape was strong and they looked determined but we didn't pass and move with the conviction we needed to."
Jermaine Easter came closest to scoring for the Lions when his shot hit the underside of the bar in the eighth minute.
"We had a lot of the ball, we tried to move it but maybe we weren't fluent enough and didn't have enough movement," Holloway added.
"We created two great opportunities – at Fulham we created one and took it, which got us a great result, but we didn't take our chances and they counter-attacked us.
"If that had gone in from Easter [it would have been different]. That's probably why Ipswich were offered so much money for McGoldrick because he had one chance and scored.
"We should have scored, we didn't and then one ball over the top leads to a goal. They won the flick, McGoldrick got hold of it, joined the play quicker than my lot and scored.
"But how dare he outrun us? How dare we get out-run by any other person wearing a different colour shirt? That's how simple it is, so yes I'm disappointed.
"Does that normally happen? No, and we've got to put that right. Goals change games so enormously at this level that you would not believe it.
"The second goal was absolutely vital in this game and it came from our totally useless set-piece from our point of view.
"Someone's got a free foot on it and we needed that, but we didn't look like getting it. That's what upsets me.
"We've got to get strong. We've got a long way to go. Everybody was excited and now they're not. We'll dust ourselves down and have a go against Reading.
"I'm going to be one point short of what I wanted because I asked the lads for seven points from the next nine. We've got to win these next two to get six now.
"They've let me down – but not badly though, because the best team won. Ipswich stuck to their task better than we did.
"Who looked more likely to get the third goal? It certainly wasn't us."
