The Swans completed a superb week as they signed off with a comfortable 2-0 win at newly-promoted Crystal Palace to rise into the top half of the table.
Michu opened the scoring with the quickest goal of the Barclays Premier League season as he fired home with just 80 seconds on the clock.
The Swans went close to adding to their lead in the first half, Chico Flores hitting the post before seeing another effort chested off the line while Angel Rangel's powerful volley was tipped over by Julian Speroni.
But the Swans ensured they would be taking the points back to South West Wales in the 48th minute as debutant Alvaro Vazquez teed up Nathan Dyer, and the winger slotted home from close range.
The victory, a second consecutive away win in the league, completed a week which started with a 2-2 draw with Liverpool at the Liberty before that famous 3-0 victory over Valencia at the Mestalla in the Europa League.
Next up for the Swans is a trip to Championship side Birmingham City on Wednesday as Michael Laudrup's side begin their defence of the Capital One Cup.
Michael Laudrup handed Spaniard Alvaro Vazquez his debut from the start.
The striker, who arrived on deadline day on a loan deal from Getafe, was given the nod as record signing Wilfried Bony moved to the bench due to a slight rib problem.
Other than that, Ashley Williams returned to skipper the side after missing the Europa League win in Valencia three days ago while Ben Davies and Jonjo Shelvey were also back in the starting XI.
In the final change, Wayne Routledge was on the wing against the club who he started his career with as he made his first appearance at Selhurst Park since leaving the club in 2005.
Palace boss Ian Holloway opted for a two-man forward line as Cameron Jerome partnered Arsenal loanee Marouane Chamakh up front.
Barry Bannan and Adlene Guedioura returned to the starting line-up while Wales international Jonathan Williams and left-back Jonathan Parr were still sidelined through injury and midfielder Kagisho Dikgacoi was suspended.

The Swans, fresh from their superb win in Valencia, got off to the perfect start after just 80 seconds.
In a move that started with Chico Flores' pass to Michu, the Spaniard then touched onto former Eagles winger Wayne Routledge, who found Jonjo Shelvey on the edge of the box.
The English international's pass deflected off Routledge to Michu, and his shot was too powerful for Julian Speroni, who could only get a slight touch to it as it found the top corner.
It almost got even better for the Swans just a minute later as Chico's low volley from a corner hit the post and then he saw another effort chested off the line as Palace were rattled by the visitor's frenetic start.
The Swans were enjoying the best of the majority and possession as they dictated the tempo of the game, though neither side really troubled each other's goal until after the half-hour mark.
That came via Michu's half volley which deflected over for a corner following some fine play by Routledge to keep Shelvey's pass in play.
From Ben Davies' corner, Michu rose the highest but he couldn't keep his header down.
Palace's first real effort at goal came via Adlene Guedioura, who struck straight at Michel Vorm from a 25-yard free-kick.
At the other end, Speroni had to be alert to palm a powerful Angel Rangel volley over the crossbar after Cameron Jerome's headed clearance dropped to the Spaniard following a corner.
That proved the last action of the half, which would have pleased Laudrup after his side dominated the opening 45 minutes.
Half-time: Palace 0 Swans 1
Ian Holloway made a change at the break, with Jose Campana replacing Damien Delaney, who was forced off with an injury picked up seconds before the break.
That meant skipper Mile Jedinak dropped back into defence with Campana slotting into the heart of midfield.
But, just like the first half, the Swans made a breakthrough early on.
Just three minutes in, Michu found Alvaro Vazquez down the right, and when the Spaniard's initial shot came back to him, he squared to the unmarked Nathan Dyer, and he sidefooted past Speroni from six yards.
The Swans were clearly on top, and they looked for another goal as Shelvey's exquisite crossfield pass found Michu, who controlled superbly but the recovering Jedinak got back in time to block his attempt.
Then Vazquez had a golden chance to make it a scoring debut as Michu and Dyer combined to set up the striker, but he skied his 18-yard over the crossbar and into the home crowd behind the goal.
That proved to be Vazquez's final input as he was replaced on the hour by Jonathan de Guzman, which meant Michu moved up front.
Holloway responded by making a double change as the Palace boss looked to inject more attacking options into his side.
On went Jerome Thomas and Dwight Gayle, who took the places of Barry Bannan and Jerome.
Alejandro Pozuelo, impressive in the win at Valencia, was then introduced for the last 20 minutes in placed of scorer Dyer.
Pozuelo settled into the game quickly, teeing up Shelvey but the midfielder couldn't keep his effort down.
Laudrup made a final change in the 77th minute, Leon Britton on for the impressive Jose Canas.
With the home side looking for a way back into the game, the Swans had another opportunity to finish them off as Michu latched onto a through ball and was one-on-one with Speroni, but the Spaniard's chip was took weak and the keeper easily collected.
Speroni then had to deal with Pozuelo's 20-yard shot, and then Michu lost control of the ball as he was put in on goal again, but the defence cleared the danger ten yards out.
That was the end of the action, though, as the Swans celebrated another three points in the league which took their tally up to seven from five games.
