Millwall boss Kenny Jackett believes his side can launch a late Championship play-off bid after thumping Burnley 3-0.
The Lions' win at Turf Moor puts them within seven points of the top six after denting the Clarets' own hopes of making ground on Nottingham Forest.
Two second-half goals from Paul Robinson put the game almost to bed and then Andros Townsend made sure of the points and compounded Burnley's misery with a third with just minutes to spare.
It was a fine display from the visitors which ended the hosts' three-match winning run.
"It keeps the play-offs open to us and that is an achievement after coming up from League One," Jackett said.
"We have nothing to lose. We have to keep believing, but a high number of points is required.
"If we attack it like we did today, and with the same appetite, then we have to keep believing we have a chance.
"From our point of view now we want to make sure everybody stays fit and this type of week can galvanise you.
"Our away record recently hasn't been as good as it should be - but we haven't been able to get over that line."
Jackett's side inflicted a first defeat in seven on Burnley, much to the displeasure of the home fans, which the Millwall coach felt helped to push them on.
He added: "It was a very pleasing performance. We managed to keep the crowd quiet which was important.
"Burnley are a very strong side, a side I rate highly and once they start to play they can step up and put on very good performances."
Meanwhile, Burnley boss Eddie Howe said his side, despite the setback, will look for a response at the earliest possible opportunity.
However, he was less than pleased with the way in which they conceded after both of Robinson's goals came from corners.
"It was a disappointing performance and we were below-par today," he said.
"But credit to Millwall, they defended very well, got bodies behind the ball and made it difficult.
"Their game-plan worked well and we lacked our spark today, we gave the ball away too often.
"We conceded the goal in our best spell and it is a real disappointment to concede from a set-play.
"It's back to the training ground to try and put that right."
Burnley remain seventh following that defeat but, with two games in hand, Howe is more than confident they can maintain their play-off challenge.
"We have to try and bounce back," said Howe. "We are still in a good position.
"Sometimes you learn more from a defeat and we have learned a lot today.
"An important part of winning is how you deal with setbacks and we need to try and find the intensity that was missing today."
