Cardiff City produced a stunning win over 2011-12 champions Manchester City to claim their first victory in the Premier League.
After falling behind to Edin Dzeko's powerful 52nd-minute opener, Aron Gunnarsson equalised after Joe Hart blocked Fraizer Campbell's shot.
Former Manchester United youngster Campbell then scored twice in eight minutes to put the home side in charge.
Alvaro Negredo set up a grandstand finish, but Malky Mackay's men held on.
The final whistle brought with it scenes of celebration from the packed crowd at the Cardiff City Stadium as the Bluebirds won in the top flight of English football for the first time since they were last there in 1962.

But it was a chastening experience for new Manchester City boss Manuel Pellegrini, whose side brushed aside Newcastle 4-0 on Monday but surrendered a one-goal advantage in the Welsh capital.It was also the first top-flight victory for Mackay, who guided his team to the Championship title last season.
The one disappointing aspect of the victory over the Magpies was an injury to skipper and defensive lynchpin Vincent Kompany.
And the Belgium international was sorely missed on Sunday, with midfielder Javi Garcia deployed as a makeshift defender.
It was an afternoon packed with emotion - starting even before the game kicked off when a group of fans staged what they termed as a pre-match march to celebrate the club's heritage; one that was synonymous with playing in blue rather than the red that the club's Malaysian owners have opted for.
But no matter their gripe over the club's identity, home fans could have had no complaints with the manner in which their players took the game to Pellegrini's side.
