Delighted AFC Wimbledon boss Neal Ardley always felt his in-form side would get something from the London derby at Dagenham.
They grabbed all three points to ease themselves out of the League Two drop zone thanks to French sub Kevin Sainte-Luce's late goal in a 1-0 victory.
Ardley said: "I thought we played really well throughout the game. We created two or three good chances in the first half, while at the other end we were hardly troubled. In the second half we defended set pieces well, we put our bodies on the line and in the end we've managed to secure a great three points.
"Everyone can see we're so much fitter and stronger now, there's a real belief amongst the players. We've got that momentum now, and to be honest I always felt we were capable of getting something here.
"We can't get too carried away though. There's still another five more wins to go and this league can be very unforgiving. We've just got to keep going and keep trying to get those wins, hopefully well before the end of the season."
Roared on a by a tremendous 800-strong travelling army, the Dons enjoyed the better of a largely disappointing first half. Sainte-Luce won the game with 10 minutes left as he drilled home from 25 yards after Chris Hussey's corner-kick was not sufficiently cleared.
Daggers' goalkeeper Lewington almost nicked a point in stoppage time but as he went forward for a last-gasp corner-kick his goal-bound shot was blocked by Midson.
Home boss John Still said: "For some reason we just couldn't get going. There was too much edginess out there and in the end we've been punished for putting in a poor performance.
"We just didn't work their keeper nearly enough. Wimbledon have been going well of late and we knew we were in for a tough game, but we've not been anywhere near competitive enough.
"In a big home derby fixture like this I was looking for more. There was a good turnout from the supporters but they'll be going home really disappointed with an outcome like that."
