There have to be a couple more Man City goals in this...

The big question remains whether City can keep a first clean sheet for eight matches.

Same again from City.

Brilliant from Kevin de Bruyne as he flicks the ball into David Silva's path.

The midfielder has a curling effort palmed away by goalkeeper Vito Mannone.

Can Sunderland do anything about it?

You would have to think not...

Before today, Manchester City were unbeaten at home against Sunderland in the top flight for 13 matches spanning 34 years, winning 10, drawing three and scoring 36 goals. 

That looks like being extended...

That could not be much easier for Manchester City.

They have been brilliant going forward - defensively, not entirely convincing still.

"Raheem Sterling looks onside to me. A lot of people have been talking about Sterling needing to time his runs better, but on this occasion he did really well and is onside in my opinion. In line with the last defender."  

This is absolutely relentless from Man City.

Every time Kevin de Bruyne gets the ball on the right, you expect a goal.

Almost a third assist for Kevin de Bruyne...

He slips Raheem Sterling through on goal, who finishes with aplomb.

Offside though - just.

Kevin de Bruyne is simply outstanding.

The home fans rise to applaud him as he produces a sublime spin in a tight corner. Comes to nothing, but he already has two assists to his name today...

Sunderland are getting in behind City...

This time Fabio Borini gets in but his low shot from an angle is easy for goalkeeper Joe Hart.

City don't look great defensively though.

A rare Sunderland chance as Steven Fletcher diverts Patrick van Aanholt's low cross over the bar.

At the other end, David Silva dances through Sunderland's defence but strikes inches wide from 20 yards.

Domination? Not half.

Things don't look particularly rosy for Sunderland do they?

The team that has been 19th in the Premier League on Christmas Day has gone on to be relegated in each of the last four years.

Where are Sunderland? Yes, 19th... over to you Mr Allardyce.

"It's disappointing this from Sunderland. It's not acceptable. This form is going to see them relegated. 

"It's another wonderful ball from Kevin de Bruyne but there was no physical challenge on Wilfried Bony. When you play for a Big Sam side, those are the details you work on. So far, Sunderland have let themselves down."

Regretting that journey to the Etihad, Sunderland fans?

This could get embarrassing. Kevin de Bruyne floats in a cross from deep and Wilfried Bony is unchallenged to guide the ball home with his head from the penalty spot.

We haven't even hit 25 minutes yet.

So close to a lifeline.

Fabio Borini does brilliantly on the right. He twists and turns and finds Danny Graham inside the penalty area.

The Sunderland striker throws himself at the ball and heads just, just wide of the net.

"Huge credit to Raheem Sterling for the first Manchester City goal. To be able to direct the ball so accurately when the ball had so much pace on it, that is a real skill. 

"On the second goal though, Sunderland just backed off Yaya Toure. I don't think you can have a go at the goalkeeper, but Sam Allardyce will be disappointed with the defending."
