Boss Paul Lambert felt a slow start at Ewood Park lead to their downfall as they slipped to a narrow 1-0 loss to Brighton.
Bobby Zamora's third minute strike was the only goal on a disappointing afternoon at Ewood Park.
The manager was unhappy with the team's performance and knows they have to perform better in front of the home fans.
"We start really slow which was never the game plan and it was a poor goal to give away in the first few minutes," Lambert told Radio Rovers.
"We had some chances to get back but the first half was too slow. You can't start a game the way that we did and try to turn it around like that.
"We can't start games as slowly as that and think we can pass the ball back, that is not the way we want to play. We want to be on the front foot, we want to get after teams, but we certainly never did that.
"The second half was better, we played in their half, but it was still way short, it still wasn't enough.
"I always go out to try and win, we are at home and we have to do a lot better in front of our own fans.
"They deserve more than they are getting, that is the most disappointing thing. We let them down again.
"Did we deserve to lose the game today? Probably not. But we didn't do enough to win it."
