Dean Saunders admitted Doncaster let an opportunity to ease their relegation fears slip at Crystal Palace.
Rovers passed up a host of chances to take the lead and ended up needing a late equaliser from Chris Brown to cancel out Jermaine Easter's strike and snatch a 1-1 draw.
A point was not enough to stop them dropping back to the foot of the npower Championship and games are now running out for Saunders' side, who are four points from safety with seven games remaining. The Rovers boss said: "It's a disappointing result. We could have been 5-0 up after 15 minutes. I lost count of the chances we had."
He added: "But for all the football we played what counts is what happens in each box and we didn't do enough.
"It's about results and we are making it harder for ourselves, that game was there for the taking."
A point was also not much use towards Palace's already slim play-off hopes, but manager Dougie Freedman is not planning for Wembley anyway.
"We're not strong enough for the play-offs, we are still growing as a club and we will be ready one day - but I don't know when yet," he said.
"When we lost our centre-halves I would probably have taken a point, but when you go one up you expect to win the game.
"However you have to give credit to Doncaster, they dug in and got a point."
