Boss Chris Wilder thanked the Cobblers fans for their rousing support as Burton Albion were beaten 1-0 at Sixfields in Sky Bet League Two.
Northampton’s survival hopes were boosted significantly by the hard-fought win over the Brewers, which was secured by a 42nd-minute goal from striker John Marquis.
Town are still second bottom, but having been six points adrift of safety eight days ago, are now level on points with rivals Wycombe Wanderers with four games of the season remaining.
The atmosphere inside Sixfields was electric in the second half of the win over Burton, and was a far cry from the general mood of doom and gloom that followed the 3-0 home defeat to Bury a fortnight ago.
And Wilder said: “On behalf of the players, the staff and everybody connected to the club, I want to say thank you for the support today. It was magnificent.
“You sometimes get a vibe when you walk through a club on match day, and I thought the vibe here today was a really good one.
“We started off on the front foot, and the supporters really gave us a lift, especially in the second half.
“It became a long second half, my watch never shifted for about 25 minutes, and especially going into the three added minutes.
“But we have beaten a decent side today that had an opportunity of going into the top three, so we have had to work hard for the win.
“And we have definitely done it together, so I thank the supporters for the help and backing they have given everybody on the football pitch.
“We are in a tough situation, it has been the same all season, and we are going to have to do it together. We did that last week at Accrington, and we have certainly done it together today.”
An added bonus for Wilder and also the Cobblers supporters was the return to playing action of captain Kelvin Langmead, who has been out of action since May last year after undergoing knee surgery.
Langmead was given a standing ovation when he replaced Chris Hackett after 77 minutes, and Wilder said: “We were only ever going to use Kelvin for 15 or 20 minutes, and he has done extremely well to get back to this stage in his career.
“What he has gone through, the boy deserves an enormous amount of credit, and I like players like that, players that are willing to put everything on the line for the club.
“And when he came on, he headed and booted everything and saw us over the line.”
