Greg Abbott has described Carlisle's football in the first-half at Oldham as "some of the best of the season".
The Cumbrians raced into a two-goal lead at Boundary Park and held on after the break to win 2-1 and pull 10 points clear of the League One drop zone.
"Oldham are fighting for their lives and we were well on top, playing great football," he told BBC Radio Cumbria.
"Oldham reacted and we had to deal with a barrage at times in the second half, but the boys stood firm."
After the recent goalless draw at Sheffield United, Abbott heaped praise on young goalkeeper Mark Gillespie.
The 21-year-old shot-stopper pulled off several notable saves against Oldham, including two one-on-ones.
"The way Gillespie has come through a difficult spell is fantastic," Abbott said.
"A lot of credit has to go to the fans and the other players for sticking with him after a sticky spell."
Carlisle now face trips to current top two - Doncaster and Bournemouth - either side of a home game with Preston.
"Beating Oldham is massive because it makes the upcoming matches ones to look forward, not games that we should fear," Abbott added.
"We've had a tough season but the spirit shown on Saturday and the appreciation that got from the fans makes it all worthwhile."
