Swansea manager Garry Monk says guiding his side to a 3-0 victory over Cardiff in the south Wales derby ranks as one of the proudest moments of his career.
Goals from Wayne Routledge, Nathan Dyer and Wilfried Bony secured three points that moved Swans up to 10th in the Premier League.
Club captain Monk was put in charge for "the foreseeable future" after Swansea sacked Michael Laudrup on Tuesday.
"This is my proudest part," he said. "The players were magnificent."
The win was only Swansea's second in 11 league games, but boosted their hopes of avoiding relegation to the Championship as they moved four points clear of 18th-place West Brom.
Monk, who has been with Swansea since 2004 and has made 270 appearances for them, added: "We can keep the ball as well as anyone in this league.
"Confidence is the biggest thing. Half the battle is the mentality, if you can get the mentality right the football takes care of itself.
"We need to take the belief from this game and into the games coming."
Monk said he does not know how long he will be in charge but has said that he wants the job on a permanent basis.
"It doesn't feel like an audition," he said.
"The chairman asked me to take over with the first team and I would do anything for this club - be it the under-eights, the academy or the first team. Fortunately it was the first team and there is no prouder man than me tonight."
