Swansea all but sealed their place in the group stages of the Europa League as they destroyed Petrolul Ploiesti 5-1 in the first leg of their play-off tie at the Liberty Stadium.
As with their first meeting with Malmo in the previous round, Swansea simply overwhelmed their opponents as they romped to a convincing victory.
Wayne Routledge grabbed a first-half double with Michu also on the scoresheet to give Michael Laudrup's side a 3-0 half-time lead.
An own goal from Petrolul goalkeeper Pecanha and a classy finish from Alejandro Pozuelo increased their advantage, before Gheorghe Grozav got a late consolation for the visitors.
The tie was effectively decided inside 25 minutes as Petrolul, the Romanian cup holders, floundered.
There was a hint of luck about Routledge's opener. A Jonjo Shelvey free-kick ran all the way through to the winger but Pecanha looked to have his shot covered until Ovidiu Hoban stuck out a leg to guide it in.
Michu quickly tapped in a second when Pecanha could not hold a Pablo Hernandez shot, before the latter delightfully teed up Routledge for a simple far-post header.
Pecanha then inadvertently provided the fourth as he diverted Wilfried Bony's shot over the line after the striker's effort squirmed under him, before Pozuelo raced on to a Michu pass to finish in style.
But Petrolul had the last word as Grazov, whose goal had seen off Vitesse Arnhem in the last round, produced a stunning overhead kick to beat Michel Vorm.
