Gillingham manager Peter Taylor felt his side achieved what few expected of them as they snatched a 1-0 win at Milton Keynes Dons to move into the top half of League 1.
Craig Fagan's first goal for the Gills settled the match and the result should end any lingering relegation fears as they now lie nine points clear of the drop zone.
But defeat was a real blow to the Dons' play-off hopes as they remain three points behind sixth-placed Peterborough, and they barely created a chance of note despite dominating possession throughout the game.
Taylor said: "It's an outstanding result for us and one I'm sure that not a lot of people expected - probably us as well because MK Dons are a very good football team.
"I couldn't ask any more of the players for the way that they worked and I know that on the stats there'll be loads of possession for MK Dons and not a lot for us.
"But we defended as a team and backed each other up and I'm not convinced there was a clear-cut chance for MK Dons.
"I think that is credit to the players who fought magnificently as a group and deserved a clean sheet.
"If we'd have come here with a 4-4-2 I think that they would have opened us up too much.
"There are times you have to deny them space so the players worked really well and it was a hard night for all of them."
Gillingham's winner came five minutes into the second half as Fagan swept in Cody McDonald's cut-back after David Martin had kept out Myles Weston's initial shot.
The closest MK Dons came to an equaliser was when Dean Bowditch's effort was cleared away by Leon Legge with eight minutes left.
Dons boss Karl Robinson said: "I thought our build-up play and our style was excellent - we got into some great areas.
"They've then had one shot on target and beat us 1-0.
"We've not scored at home since Oldham four games ago.
"It's basic. We were the better team by far - we've played with energy and we've played with hunger.
"The players put their bodies on the line and they got into some key areas.
"We changed the system two or three times from 4-3-3 to 4-2-3-1 to even three at the back with two up front.
"We changed a number of things and we were constantly dominant, but we can't score.
"Don't think I'm not looking for someone to do that or players to do so - I'm looking everywhere to try and find them.
"We need it because we were just not good enough in the final part of the pitch."
