Danny Wilson feels Barnsley now have the belief to escape relegation after a vital 2-1 win at fellow-strugglers Charlton Athletic.
Goals in each half from Jean-Yves M'voto and Tom Kennedy hauled the Tykes off the foot of the Championship and to within two points of their opponents, who remain just above the drop zone.
"It's the result we needed to give ourselves a chance, that's for certain," said Tykes manager Wilson.
"We had a real calmness about us, especially with the atmosphere and everything surrounding the game.
"Charlton started very well and had us on the back foot but without causing our goalkeeper too many problems.
"Then to get the goal like we did was a real body blow for them. After that we controlled it for long periods.
"It's a big psychological boost and gives us the belief we can do it. We won't get carried away but we've given ourselves a chance."
Charlton, knowing victory would lift them up to 17th and drag the likes of Blackpool and Birmingham into the scrap at the bottom, were the dominant team throughout.
But their season-long goalscoring problems cost them yet again, especially in the opening half-an-hour.
Callum Harriott was the chief culprit when he fluffed a header from six yards out, while Johnnie Jackson and Marvin Sordell also missed presentable opportunities.
The Tykes, by this time, had barely set foot in Charlton's half.
But if the Addicks' lack of goals has been their Achilles heel this season, their defending from corners has not been much better.
There was an air of inevitability around The Valley when, from their first real attack, Barnsley forced a 32nd-minute corner.
Dale Jennings swung the ball across and M'Voto, the French defender built like a cruiserweight, caught Charlton with a sucker punch as he powered a header downwards and past the helpless Ben Hamer.
More half-chances came and went but Barnsley got a break in the 63rd minute when Tom Kennedy's cross flew straight in.
Astrit Ajdarevic pulled one back in stoppage time, but boss Addicks Jose Riga was again left to reflect on their goalscoring problems.
"We cannot face more reality than today," he said. "We had control of the game, but we have to score before we concede. We conceded a goal from their only opportunity in 45 minutes.
"We deserved more. Callum had a header, Jacko and Marvin, we had enough opportunities. Barnsley are not an easy team but we have to be efficient.
"We have young players so maybe it's the pressure of the situation. But we still have destiny in our hands. They needed to win, we did not."
