City clinched the title without kicking a ball as their arch rivals United slumped to a shock 1-0 defeat against West Bromwich Albion yesterday.
His players were spread across Europe as Jay Rodriguez scored the goal that sealed City's title, but Kompany, the captain, watched with his City-supporting wife, Carla, their two children and other family members at his Cheshire home.
"It's the same feeling as the first time, you can't describe it", Kompany told Sky Sports.
Word quickly got around through social media and City fans queued outside a venue still advertising United's televised clash with the Baggies in a bid to join fellow supporters inside, where the players were seen belting out Oasis' Wonderwall and being serenaded by supporters expressing their delight and gratitude.
Kompany, at home in Manchester, revealed many of his team-mates had flown off for mini-breaks to see family and friends after being given three days off.
"It's been a fucking long journey... especially if you've been a blue for more than forty years in your heart!"
"We were exhausted, not just physically but mentally as well and a lot of big characters stood up today and that gives me a lot of pride again to be able to share these moments with this team".
"Just one more time, come on City!"

"You can't take it for granted...before you know it, it's gone".
"I've never been able to retain a title and I want to see if this team can be even more successful".
City though have never successfully defended a league title and Kompany is hoping he can help build a dynasty at the Etihad.
"Any player under him has had success because of him and how they've improved as individuals".
The former Barcelona and Bayern Munich boss had already led City to League Cup final victory over Arsenal this term.
And of the three title-winning celebrations he's taken part in, Kompany said: "The first title was the biggest event ever for the Club, for our fans and enabled us to build to what we are doing today".
"I think we share one thing maybe, the hunger and desire to never be satisfied", said Kompany.
"When I was 20 I would have been a ideal player for him".
