Match ends, Swansea City 1, Manchester City 3.
Swansea City 1-3 Manchester City
Premier League leaders Manchester City maintained their perfect start under Pep Guardiola with victory at Swansea.
Sergio Aguero fired the visitors in front before Fernando Llorente scored his first Swans goal with an emphatic half-volley four minutes later.
Aguero netted his second goal with a penalty after Mike van der Hoorn elbowed Kevin de Bruyne, who later limped off with a hamstring injury.
Raheem Sterling added a classy third after a quick counter-attack.

Guardiola's men had looked a little below par with the score 1-1 at half-time, but an authoritative display after the break underlined their title credentials.
The Spaniard becomes only the second manager to win his first six Premier League matches after Carlo Ancelotti, who did so as he led Chelsea to the title in 2009-10.
Swansea's defeat, meanwhile, leaves them hovering above the relegation zone by one point - albeit after an improved performance which may have eased the pressure on beleaguered head coach Francesco Guidolin.
Man City avoid a first hiccup
Manchester City had already beaten Swansea in the EFL Cup on Wednesday to make it nine wins from their first nine games under Guardiola, but this was a far more important fixture for both sides.
While the midweek cup match was a battle between two shadow sides, the likes of De Bruyne and Sterling were restored for this game - and, most significantly, so too was Aguero.
Having served a three-match ban for elbowing West Ham's Winston Reid, the Argentina forward struck after just nine minutes, swivelling inside the penalty area and finishing powerfully through the legs of Lukasz Fabianski.
Manchester City poured forward with typical pace and fluidity but they struggled to create many clear chances, one of which was uncharacteristically dragged wide by the recently irrepressible De Bruyne.
However, Guardiola's side addressed those issues with a ruthless second-half performance.
After Aguero cheekily wrong-footed Fabianski from the spot, Sterling finished a sweeping breakaway with a flourish, flummoxing Kyle Naughton with a step-over before rolling the ball past Fabianski.
Whereas Manchester City breezed into this fixture with the confidence of serious title contenders, their opponents were vulnerable.
Swansea's tally of four points was their lowest after five matches of a Premier League season, casting grave doubts over the future of head coach Guidolin.
His precarious position means the Swans have already considered potential successors, such as Ryan Giggs, but the hosts' spirited display suggested the players were battling to save Guidolin's job.
They frustrated their visitors with an energetic first-half display, capped by Llorente's firmly struck first goal for the club, and Guidolin and the home fans felt aggrieved when referee Neil Swarbrick awarded a penalty after judging Van der Hoorn - otherwise solid on his Premier League debut - had elbowed De Bruyne.
However, the reality of Swansea's situation bit in the second half as Manchester City's ruthless showing inflicted a fourth defeat from six Premier League games for Guidolin's men, leaving them staring at another relegation battle.
Man of the match - Sergio Aguero (Manchester City)
David Silva's influence grew in the second half but it was Aguero who made the most incisive contributions, scoring two important goals to ensure City avoided dropping points for what would have been the first time this season.
What they said
Manchester City manager Pep Guardiola said: "We played very good, but we missed a lot of final passes and that happened a lot of times in the first half.
"You have to win the ball, use the ball and use the counter-attack. It is the first time we have been 1-1 at half-time and we spoke of how we had to be like a team and in the second half we played really well.
"Sergio is quality. His first step, second step in the box is so good and that is why he is one of the best strikers in the world but I want to help him improve his game."
On De Bruyne, Guardiola added: "I think he is injured, that's why we have to have a big squad as everyone will help us.
"It's a pity - he is important for us. How he reacted, it looks like it was a muscular injury, but I'm not a doctor."
Swansea City manager Francesco Guidolin said: "We played a very good game and for one hour we were at the same level as Manchester City and they are the best team in the UK.
"In front of us we have a good future. I know my job and after four, five or six defeats it it not easy but I am confident as we have played a good game today."
On the penalty decision that saw his side fall 2-1 behind, Guidolin added: "I'm not a judge. If the referee says this I have to accept it. For me it is not a penalty but that's not important, the important thing is my team played a good game."
