IAN Holloway says Millwall cannot afford to lose to Birmingham tonight.
The Lions, sitting third from bottom, are running out of time to turn their season around.
Defeat to Leeds United on Saturday left them bottom of the Championship form table over the last ten games ahead of the Blues' visit to The Den.
Defeat under the lights on Tuesday would leave Millwall cut adrift at the bottom and give Birmingham, currently 20th, an eight-point lead over Holloway's side.
"In my opinion, we cannot afford to lose this game," the Lions boss admitted. "If we don't win it, but we get a point, we can still catch them. If we lose, it will be very, very difficult."
Holloway bemoaned Millwall's luck in front of goal following the 2-1 defeat at Elland Road last weekend but says little has to change for results to pick up.
He said: "We have got to make a change – and the change is to do the same as we have been doing, except score the first goal and things will turn around.
"The stats from the game on Saturday were quite embarrassing. We beat them on every stat apart from the one that said 2-1.
"I strongly suggest the only thing we need for our luck to change is to be more positive.
"If DJ Campbell's goal had been the first goal, it would have won us the game because Leeds would have absolutely bottled it.
"They had three shots and scored from two of them. That cannot continue – it is impossible. How we were 2-0 down at half time I just do not know, and I've watched the game again."
However, Holloway has targeted a few areas where there is room for improvement.
He added: "What I will say is that when we had a chance to attack as a front five, we won it back, we were steaming in at them, they only had three back but we ran in straight lines.
"We didn't make enough cross-over runs – like Samuel Eto'o did at the weekend – and I will be showing my team that.
"Also, the timing of the set pieces. The movement was better but we didn't get the timing right, so we're going to practise that until we're blue in the face.
"When you don't get what you want, what happens to you? I know what happens to me: I get more determined."
