Millwall manager Kenny Jackett was full of praise for his side after their famous 2-0 win at Leeds - but warned there is plenty of hard work still to be done.
The Lions are now third, three points behind Leeds, after goals in each half from Steve Morison and Shaun Batt secured their first victory at Elland Road in 22 years.
"It was a very good performance and I am proud of the players," said Jackett. "They worked very hard and deserved the victory. We've had a good run and now we need a sprint finish."
He added: "It is a big result against Leeds and takes us to 68 points. Over the last four years it has taken 75 or 76 points for sixth place and anything up to 90 for second so there is a lot of hard work still to do."
Leeds manager Simon Grayson admitted his side were "not good enough" after seeing their automatic promotion hopes dealt a blow.
Grayson said: "It wasn't good enough. Over the course of game they were the better team. They were hard to beat, got in tackles and with the ball they were better.
"We have players who can do a lot better and they didn't do it. When we're at our best we pass it well with flair and imagination and we're hard to beat as well - and we didn't do any of those things."
Grayson, who must lift his players in time for Saturday's clash at leaders Norwich, added: "We knew the significance of the game and we knew Millwall were a good side.
"We knew what it was about, but we have to roll our sleeves up for the weekend. We're still in a good position and we have to come out achieve what we set out to achieve at the start of the season."
