Bournemouth manager Eddie Howe said Saturday's shock win over Chelsea was his side's most important result in club history.
The Premier League minnows hadn't won since September, a stretch of eight league games, but Glenn Murray's 82nd-minute winner moved them out of the relegation zone on 13 points from 15 games.
Asked about the magnitude of the win for a club who have flirted with extinction, Howe said: "I think it's at the very top.
"We've never been in the Premier League before, so when you come to the champions and beat them, I think it must rank as the best individual result of the club's history.
"I'm very pleased this group have been able to achieve this."
Howe said the result meant even more for the Cherries given the injuries to key personnel this season.
"It gives the players some reward for how hard they've worked," Howe added. "It's only one game but it does give us a huge boost going into the Christmas period."
Howe said his strategy of taking the game to Chelsea paid off in the end.
"We tried to impose ourselves on Chelsea. We did that, we defended well, we were very good with the ball, countered well, and gave them problems," he said. "They made some changes, and the strength of their subs made a difference. But we didn't succumb to pressure, then our moment came from a set piece.
"We scored from a set piece which is not really something we've done this season, so even though it was scrappy I was pleased to see it go in."
Chelsea boss Jose Mourinho felt the Blues should have had a penalty before Murray's winner when a Diego Costa cut-back hit Simon Francis on the arm.
But Howe disagreed with Mourinho's view of Chelsea's penalty appeal.
"I think Simon's committed to his slide," he said. "His arm's there, it's not moved towards the ball. I think that would've been extremely harsh."
