The Swans coach says his players were "magnificent" after beating their local rivals 3-0 in the South Wales derby at the Liberty Stadium
Monk, who has played in all four divisions during 10 years as a player and club captain with Swansea, was thrust into the Liberty Stadium hotseat after Michael Laudrup was sacked on Tuesday.
Goals from Wayne Routledge, Nathan Dyer and Wilfried Bony gave Monk victory in his first game in charge and he was quick to praise his players.
"I just said to the boys, there's probably not a person prouder of them than me right now – for the club, for the fans and for them themselves," he told reporters.
"The bottom line is it's about football, isn't it? Everything goes on outside, and I've been through it myself as a player, but everything that goes on in that changing room stays in that changing room.
"Those boys were magnificent, I couldn't have asked for more from them."
While acknowledging the need to adjust his own mindset to that of a manager, Monk revealed training this week was designed to take the Swansea players' minds off the turmoil surrounding the club and geared towards their strengths.
"I had to think about the game a bit differently," he explained. "I had to switch my mind from a player to a more tactical kind of mind, obviously with the passion.
"I said to the boys, I'm no different. I haven't changed overnight. But there's a job to do.
"This week we got them back on the training ground, isolated them there not to think about anything else and gave them training where they didn't have time to think.
"I think you're at your best as a footballer where you don't have time to think. The training was designed to be like that – to be sharp, to be intense.
"They took that out there [on Saturday] because that's exactly what they were. They were magnificent and thoroughly deserved the win."
