Kenny Jackett has set Millwall a target of at least 85 points to earn automatic promotion from League One after their significant victory over Leeds at Elland Road.
Goals from Steve Morison and Shaun Batt allowed the Lions to move to within three points of second-placed Leeds, having trailed Simon Grayson's men by 21 points earlier in the season.
Jackett was delighted with his side's performance against their illustrious rivals and hailed their 'underdog' spirit, but he is aware that is still plenty of hard work ahead if they want to finish in the top two.
"It is a crucial time for us, the end of the season when you really do need a sprint finish," Jackett told Sky Sports 1. "It starts our last 10 games off very well.
"Obviously it is against one of our competitors so it claws them back somewhat. To be able to come to Elland Road and play as well as that, I'm very pleased with the players and what we have to do now is look forward."
He added: "You just keep working. I don't particularly look at anyone else. I look at a points total as well and we are going to need 85-plus to get second in this league, I think.
Dream come true
"That puts us on 68 so we need to be up there and competing in our last nine games."
Jackett said of this team's spirit: "Millwall is a good underdog and were a good underdog again tonight."
Defender Paul Robinson said: "It is a massive result. It is a big victory to come here and keep a clean sheet and to beat Leeds at Elland Road is a very proud achievement for the boys."
Goalscorer Morison, who joined Millwall from non-league Stevenage last summer, said: "It is like a dream come true. You dream of playing places like this." He added: "It is fantastic and I enjoyed every minute of it."
Robinson said on the prospect of automatic promotion: "There is always a possibility, while it is mathematically possible.
"We are just going to keep going, keep focusing on the next game and it is a big one against Stockport on Saturday."
