Millwall manager Kenny Jackett refused to declare his side safe from relegation despite Alan Dunne's late winner giving the Lions a 1-0 npower Championship victory over 10-man Leicester at the King Power Stadium.
The visitors failed to make their numerical advantage count for 85 minutes following Wes Morgan's dismissal in a surprisingly even contest, until Dunne popped up to coolly slot home Richard Chaplow's cutback for his first goal in three years.
The win takes Millwall to 50 points, usually considered enough to avoid relegation, but Jackett insists there is still work to be done in the league before the Londoners can focus on their FA Cup semi-final against Wigan at Wembley.
"I think it's going to take more than 50 points," said Jackett, whose side have now gone six and a half hours without conceding a goal.
"We're 50 points with nine games to go and we'd rather get safe sooner rather than later.
"We want to go into that game [against Wigan] with good form, some confidence and playing well.
"I've thought for a little while that 50 points won't be enough to keep you up. It does look like every club at the bottom is going to fight to the end. Fifty points is something that you look for but we're on 50 points with nine games to go so if we finished on that I'd be very disappointed."
Jackett admitted his side had struggled to break down a resilient home side, particularly in a second half which quickly became bad tempered; the visitors perhaps lucky that Liam Trotter stayed on the pitch after a late lunge on Jeff Schlupp.
"We started brightly and I don't know if we surprised Leicester in that but we should have been a couple of goals ahead by half-time," he added.
"Not taking those opportunities looked like it was going to cost us and it did seem as if the game was petering out into a nil-nil draw.
"I'm very pleased for Alan Dunne, who's come back into the side in recent weeks and done very well for us defensively, but to pop up and finish with such composure showed terrific quality.
"I think his last one at Walsall was a cracker as well so when he does score their good ones and to get the winner today is a crucial one."
Leicester boss Nigel Pearson was left to rue a sixth straight game without a win as his side's promotion hopes continue to crumble.
There were no complaints about Morgan's sending off; referee Stuart Attwell was left with little choice after the Foxes captain bundled over Andy Keogh with only three minutes on the clock.
But the home side failed to make their chances count, with Michael Keane and Ritchie De Laet seeing their efforts cleared off the line by Shane Lowry and Danny Shittu.
At the other end Kasper Schmeichel had to be alert to keep out Lowry's free-kick and efforts from Rob Hulse and Jermaine Eater, but it said much for Leicester's failings in the final third that visiting keeper David Forde's only real test all night came from one of his own players when Trotter inadvertently headed an Anthony Knockaert free-kick towards his own goal.
"I could bemoan a number of things but I think it's pretty unfortunate tonight," said Pearson.
"The players have worked very hard to get something out of the game and to concede a goal so late is, I think, quite cruel. I don't think the players deserve that tonight.
"The players have shown a lot of desire to play in a positive fashion despite going down to 10 men. It's not going for us at the moment but we've got to keep working hard.
"We're not scoring enough goals. We have seven games left and we're losing games by the odd goal. It doesn't mean defeats are any easier to deal with.
"You've got to be careful not to pigeon-hole tonight's performance along with some of our other recent performances; I think we've created some good situations tonight playing with 10 men and still looked pretty dangerous."
