As United's players trudged off at Sunderland contemplating a first trophyless season since 2004-05, the biggest party since 1968 kicked off for the long-suffering sky blue half of the city.
"Five minutes from the end I did not think we could win this game. We deserved to win this championship," City manager Roberto Mancini told Sky Sports.
"After 44 years I dedicate this to all our supporters."
Captain and central defensive rock Vincent Kompany, a 6 million pounds ($9.7 million) bargain in the estimated half a billion pounds invested on players since Abu Dhabi's Mansour bin Zayed Al Nahyan bought City in 2008, shared the feelings of most of the 4?,000 fans witnessing an afternoon of drama.
"I want to say it is the best moment of my life but if I'm honest then I would say please never again this way," he said.
"We have been so good at home all season but in the second half we just couldn't get through the QPR defence.
"Did I give up? No, I never stopped believing. When Edin Dzeko scored to make it 2-2, it reminded me of our late goals against Tottenham and Sunderland."
