Fresh from demolishing Valencia at the Mestalla, Michael Laudrup urged his players to re-focus on their return to domestic action at Selhurst Park.
They did just that, and in some style, outclassing the Eagles from the outset in a win that in no way reflected their dominance.
It took just 80 seconds for Michu to set Swansea on course for a fourth consecutive win against Palace, rifling home right in front of Ian Holloway - the Palace boss having taken up a position in an executive box behind the goal as he completed a two-match touchline ban.
He would have been forgiven for watching the first half through his fingers, with Chico Flores rattling the post moments later, before Michu and Angel Rangel came close to netting.
Dean Moxey was also fortunate not to give away a penalty in strikingly similar fashion to the one he conceded on the opening day against Tottenham - the decision that led to the Holloway comments which led to his ban in the first place.
The Welsh outfit would not be denied for long, though. With no defenders on the Palace bench and Damien Delaney forced off injured, it was all too simple for Nathan Dyer to rifle home from debutant Alvaro Vazquez's pull back in the 48th minute.
Vazquez wasted a chance to extend their lead further as the game petered out, with Swansea securing a win with worrying ease for the south Londoners.
The visitors made five alterations following their trip to Spain, with Wayne Routledge coming in against the club with whom he started his career.
It was the winger's first return to Selhurst Park since leaving the club in 2005, when he opted to join Tottenham following the Eagles' relegation from the top flight.
