Bolton boss Gary Megson said he was bitterly disappointed after watching his team slump to a first league home defeat under his tenure, going down 2-1 to Blackburn.
Captain Kevin Nolan gave Bolton the lead just before half-time with a stunning strike, but second-half goals from Christopher Samba and Jason Roberts sealed the points for Rovers.
Roberts' 90th minute winner came after he gathered the ball in his own half and rode several challenges to get in a goal-shooting position.
His effort was then slightly deflected past Bolton keeper Jussi Jaaskelainen, who got a hand to the shot but could not keep it out.
Speaking afterwards, Megson said: "In the first half I thought we maybe shaded it in terms of where the football was being played.
"But they have got some terrific players in there and second-half they were on top.
"But any team that has got Bentley in the side and Dunn in the side and Pedersen, they are going to cause you problems.
"And then when Jason came on with the strength and power that he has got, we struggled to contain him.
"And even Jason's goal, I think we had three marking Jason Roberts and I know he got a little bit of fortune for the ball to get where it did, but he showed great speed and pace to get away.
"It's got a deflection but even so we shouldn't have been in that position where we are trying to stop that."
Asked if he needed to get some new faces in and quickly to get out of relegation trouble, Megson admitted "of course we do."
But a reflective Megson added that 12 games ago Bolton were one point below Derby, whom they are now 13 points in front.
"I think in terms of whose doing what down at the bottom, we would probably be top of that half dozen group of clubs but that's our first home defeat, we are bitterly disappointed with that," he said.
"We knew that we needed to get players in before this game, before Nic (Anelka) went, before the window opened because you're not bottom of the table after ten games with five points, you're not bottom for no reason. We're not up to it, and we've got to get people in and that is what we are trying to do.
