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.
It was also the first top-flight victory for Mackay, who guided his team to the Championship title last season.
