The Swans celebrated the New Year with a first away win in the Premier League thanks to a 2-0 win at Aston Villa.
Nathan Dyer got the Swans off to a flying start as he capitalised on Stephen Warnock's mistake within five minutes before former Villa winger Wayne Routledge scored his first ever top-flight goal in the second half to double the lead.
It was a fantastic effort for the Swans as they outclassed a Villa team that had won 3-1 at Chelsea only days previously.
Brendan continued to switch team selection as he made seven changes to the starting XI.
After making six changes for the home draw with Tottenham Hotspur, Brendan brought in Angel Rangel, Steven Caulker, Leon Britton, Kemy Agustien, Andrea Orlandi, Wayne Routledge and Danny Graham.
Orlandi, who made his Premier League debut off the bench at Wolves in October, got his first start in the top flight while Routledge returned to Villa Park to face his former club.
Caulker returned to the starting XI in place of captain Garry Monk, so Ashley Williams led the Swans.
Aston Villa: Brad Guzan, Stephen Warnock, Richard Dunne, James Collins, Stephen Ireland (Marc Albrighton, 69), Darren Bent, Charles N'Zogbia, Gabby Agbanlahor, Stiliyan Petrov (capt), Ciaran Clark (Barry Bannan, 85), Carlos Cuellar (Alan Hutton, 55).
Subs: Andy Marshall, Emile Heskey, Andreas Weimann, Gary Gardner.
Swans: Michel Vorm, Angel Rangel, Steven Caulker, Ashley Williams (capt), Neil Taylor, Leon Britton, Kemy Agustien, Andrea Orlandi (Joe Allen, 58), Nathan Dyer (Scott Sinclair, 78), Wayne Routledge, Danny Graham.
Subs: Gerhard Tremmel, Jazz Richards, Garry Monk, Luke Moore, Leroy Lita.
The Swans had not scored in all of their seven previous trips to Villa Park, with the hosts winning on each occasion.
But they broke that record within five minutes as Nathan Dyer latched onto Stephen Warnock's loose pass and the winger raced forward before shooting low across Brad Guzan and into the far corner.
It was a fantastic start by the Swans, but Villa looked for an immediate reaction. Darren Bent headed across goal after a neat cross, but at the other end Andrea Orlandi went close too as his left-footed drive just flashed past the far post.
The game continued to excite with both sides looking lively, Stephen Ireland seeing his shot cleared for a corner by Orlandi before Dyer saw his cross-come-shot drop just past the far post.
James Collins then headed CharlesN'Zogbia's corner straight at Michel Vorm before a sublime first touch from Dyer saw him round Warnock and cross to Danny Graham, but the striker's effort was saved low down by Guzan.
Graham went close again after a fine counter attack. Dyer led the charge, with Kemy Agustien and Neil Taylor then linking to find Orlandi in the box. The Spaniard's fine cut back reached Graham in the box, but the striker's shot just bounced past the far post.
Half-time: Aston Villa 0 Swans 1
Just like the first half, the Swans started the second period in perfect fashion.
Within two minutes the visitors were celebrating a second goal. Taylor's excellent first-touch pass sent Routledge down the left he beat Carlos Cuellar before crossing to Graham. The striker beat James Collins to get to the ball first - his shot beat Guzan but then rebounded off the post to Routledge. The winger reacted quickly, firing low into the far corner from an acute angle for his first ever Premier League goal.
Villa were then forced into the first change of the game as Alan Hutton replaced Cuellar after 55 minutes, before Brendan sent on Joe Allen in place of Orlandi shortly after.
The hosts were desperately looking to claw their way back into the contest and skipper Richard Dunne saw his header from a corner land just over the crossbar before Marc Albrighton replaced Stephen Ireland with 20 minutes to go.
The Swans were strong defensively as a team while they were also looking dangerously on the counter attack.
Forthe last 12 minutes, Brendan made another switch with the hugely-effective Dyer given a rousing send-off from the Swans fans as he was replaced by Scott Sinclair.
Dunne headed wide while Graham and then Allen were denied by Guzan as the Villa fans started to make their exit.
Despite five minutes of added-on time, the Swans held on - despite N'Zogbia's late effort deflecting off the post - to deservedly keep a cleansheet, win their first away game in the Premier League, and start 2012 in superb fashion.
