JAKE Cooper was pleased with Millwall's response to their defeat at Wigan in their 0-0 draw against Birmingham – but admitted his frustration at a lack of a finishing touch in the box.
The Lions have failed to score in four of their last seven games and have scored the fewest goals form open play (19) in the Championship this season.
Millwall would have cut the margin to Preston in sixth to four points with a win, but Cooper dismissed the idea it was a lost chance as he praised the defensive resilience of Blues, who are unbeaten in nine league games.
"I don't think you can say it's a missed opportunity," Cooper said, "They're a good side, you can tell by the run they've been on, they're not too many points behind us now.
"They came here with a game plan, stuck to it and made it very difficult for us. We were much happier with that performance compared to Saturday. There are lots of positives we can take from that and hopefully we can build on that and put a couple of balls in the net.
"It was massive to be able to bounce back and get that game in quickly after the weekend. We felt we were a bit off it on Saturday, we didn't approach the game right.
"It was really important to come here and put a performance on. I think we feel like we did that."
Millwall host Bristol City this Saturday. The Robins are three points ahead of the Lions in the table.
Cooper continued: "It's obviously a big challenge for us now. We can't really get bogged down in the points tally, we've just got to keep going. Eleven games to go, anything can happen, there's still 33 points to play for.
"We need to keep the momentum from today and kick on, try to get a little unbeaten run going and see where that takes us.
"We're not getting ahead of ourselves and looking too far forward. We'll come here Saturday ready to perform to try and get three points.
"I'm sure they'll come here knowing what to expect after the way we performed at their place. It's going to be a tough game, they're right up there as well.
"If we can take the points then it's going to do us massive favours. That's what we're going to try to do."
Millwall had 14 corners in the game, and Cooper feels they should be making more of set-piece opportunities.
He said: "We had a couple of knock-downs and situations where we could have made more of it. But give credit to them, they defended them really well. They've got some good defenders that are good at defending set-plays. We just couldn't get the final touch on it in the box."
Birmingham did get the ball in the net through Kristian Pedersen's strike, but the whistle had gone for a push by Harlee Dean on Cooper.
In the Sky Sports studios former Lions striker Steve Morison, on punditry duty, didn't think it was a foul.
Cooper had no doubt. "I thought it was a foul straightaway, to be honest. I've made contact with the ball and I've got contact, it's affected me heading the ball. I think it's a foul all day long so there's no complaints from me."
