Thank you for joining us.
Dafydd Pritchard's match report from the Liberty Stadium is here and you can follow are the reaction to today's Premier League action here.
And it is all over. That is played six, won six under Pep Guardiola in the Premier League for Manchester City.
Swansea 1-3 Manchester City
Swansea have been competitive, but there seems no way back. The penalty, which our pundits think should not have been given, changed the game as City retook the lead at 2-1, before Sterling's third.

You might think 3-1 shows a comfortable win for Manchester City, but it's been far from comfortable. The Swansea XI have played very well for their club and their manager, and tactically they've been spot on. But the penalty knocked the stuffing out of them.

Ex-Man City defender on Final Score
I feel a little bit sorry for Swansea, they have played incredibly well. The referee's decision there has swung the game.

More worryingly for Manchester City is the fact that during that last attack, Kevin De Bruyne pulled up with what looks a hamstring injury. He limps off rather gingerly with Jesus Navas coming on for him.

It should be four. Sergio Aguero sprints from the halfway line unchallenged before releasing Fernandinho. The midfielder looks to take the ball around Lukasz Fabianski, but he gets a hand to the ball.
Raheem Sterling (Manchester City)
Swansea push men forward searching for an equaliser but get punished on a quick counter-attack.
It is two attackers against one defender as Raheem Sterling sprints forward with Sergio Aguero alongside him.
Only Kyle Naughton is back and a step-over from Sterling completely bamboozles the Swansea man before Sterling calmly slots past Lukasz Fabianski. That should be game over.

Imer Cardona: To me it seems like referees in the Premier League are always looking for ways in how to affect their matches. So frustrating.
Swansea 1-2 Manchester City
That should be the third for Manchester City. But it isn't. Fernandinho runs from deep and is unmarked when he meets a corner. But he heads off target when he had to hit the target.

Another change, this time for Swansea as Modou Barrow comes on for Wayne Routledge.
Boss Francesco Guidolin is then seen crouching down, almost on his knees with his hand over the mouth.
The pressure on him is going to intensify if this score stays the same, although his side have produced a battling performance so far.

Josh: How on earth did that Aguero penalty not get called back for encroachment?! There's six players in the box!

Ex-Man City defender on Final Score
I think it's an unbelievably harsh decision to award a penalty against Mike van der Hoorn. He puts his arm across Kevin de Bruyne but there's no clenched fish or any malice. He's just getting his body in the way.
If you're giving that, then you are giving so many penalties this season. Not many of the City players appealed and that's telling.

The defender put his arm out to shield the ball, and he does make contact with the face of Kevin de Bruyne. I don't think that was intentional but the referee gave a penalty and a yellow card.
Guidolin, the Swansea manager, is on the pitch protesting. And I think he's right - for me that's a completely incorrect call from the referee.
That was the coolest penalty. Everybody stopped, including the keeper, and Aguero just dinked it down the middle.
Sergio Aguero (Manchester City, penalty)
Talk about calm. The home fans are booing, trying to put off Sergio Aguero, but the Argentine dinks a penalty down the middle. Lukasz Fabianski dives to his left, the ball goes straight on and City lead again.

On his Premier League debut Mike van der Hoorn has just conceded a penalty. Kevin de Bruyne controls a ball into the box but is met by a forearm to the face from van der Hoorn.
The defender will argue he was just trying to shield the ball, but referee Neil Swarbrick has pointed to the spot, with Sergio Aguero looking for his second goal today.
Angel Rangel goes for a hopeful one, shooting from 30 yards, but it never looks like going in as Claudio Bravo gets down on one knee to easily deal with it.
Swansea 1-1 Manchester City
Swansea's Jordi Amat is the latest to be cautioned for a foul.
Swansea 1-1 Manchester City
The chances are coming for the visitors.
The latest one falls to Raheem Sterling, who opts for precision instead of power but his side-footed effort is blocked by Kyle Naughton before being hacked clear.
The league leaders have a 100% record in the Premier League this season and are turning up the pressure.
