Sunderland' s Jack Colback has warned against complacency after his side hauled themselves clear of the relegation zone by beating Reading.
The Black Cats climbed four places to 15th following Tuesday's 3-0 win at the Stadium of Light but Colback insisted they can not afford to take their foot off the pedal.
The midfielder said: "We knew coming into it that it was a must-win game and we produced on the night.
"But that's not even half the job done. We know we are down there where we don't want to be and where we shouldn't be, and we need to start winning more games, especially here, and giving the fans something to cheer about."
Colback conceded that the defeat of their fellow-strugglers had given Sunderland some breathing space, adding: "We certainly feel more comfortable than when we were 18th, that's for sure.
"We knew how important this game was and we have won it. There's a lot of relief.
"We knew coming into it how big a game it was. We have not performed how we would have liked this season and we have not really had the rub of the green very much so far.
"It's one of the best feelings you can get in football when you win a game and
everyone is buzzing and the fans go home happy.
"It's certainly something that we want to keep on doing."
