Blackburn manager Steve Kean admitted his side need "two monumental performances" to stay in the Barclays Premier League after a 2-0 defeat at Tottenham.
Rovers remain second-bottom, three points shy of safety with just six available to play for.
Goals from Rafael van der Vaart and Kyle Walker sealed the win for Spurs, who moved back into fourth place, while Blackburn failed to muster a single attempt on goal.
But Kean, whose side face Wigan and Chelsea in their last two games, was happy with his side's commitment at White Hart Lane.
"As far as our application and effort in the game, that was there," he said.
"The normal part of our game that is normally good and of quality - getting the ball into the front two - was difficult today.
"I don't think we got any type of quality into the box. We normally do and that was the disappointing factor of the game."
West Brom were the last side not to manage an effort on goal in a Premier League fixture when they drew a blank against Manchester City in 2004, and Kean blamed the lack of quality in his side's build-up play for the toothlessness in attack.
He said: "I'm not embarrassed, I'm disappointed. We have been to many away grounds this season and have always carved out a few chances but the chances for the strikers don't come from them making the chances themselves - they come from good bits of quality before it gets into the final third."
With a crucial fixture against fellow relegation-threatened side Wigan next Monday, Kean is still confident he can guide his much-maligned team to safety.
"It is tough but we need two monumental performances and back-to-back clean sheets," he said.
"There have been many times this season that people have written us off and said it is done and dusted and we've bounced back, and we are probably going to have to bounce back with back-to-back wins and there is no reason why we can't."
Tottenham manager Harry Redknapp believes Kean has done the best job possible.
He said: "It is difficult for them (Blackburn), they are struggling and he has got a tough job there.
"It has not been easy for him and how he has had to go through the year and keep them going, it must be so difficult. I wouldn't like to be in the position he has been in.
"He hasn't been able to bring any players in and has got what he has got at the end of the day.
"Whether he was manager or (Manchester United manager) Alex Ferguson I think it would be difficult to get more out of them - he has got the best out of what he has had this season, that is my honest opinion on what I have seen of them."
The three points moved Spurs back into the top four, but Redknapp still believes it is all to play for in the hunt for Champions League qualification.
"It is going to be hard," he said.
"You never know, it is all to play for but we have got a couple of difficult away games and you just have to keep going.
"We have just got to keep going and see what happens, whoever saw Wigan pulling off the results they have pulled off."
