A few handbags between Kelechi Iheanacho and Watford's Valon Behramii after they battle for the ball - but that is the nearest we have come to any late drama here.
City are still content to sit back on their lead. Watford are seeing a lot of the ball but they are still yet to test City keeper Joe Hart.
Time for another City change. Kelechi Iheanacho is coming on for his debut, replacing Raheem Sterling... who departs to loud applause after opening his account for his new club.
Credit to Watford, they are giving this a go but City's defence is not exactly wobbling.

Watford have not had a single shot at goal today, either on or off target - all four of their attempts have been blocked. It is very hard to see them turning this game around with 10 minutes to go.
A final change for the visitors. Ben Watson, who scored the winning goal for Wigan against City in the 2012 FA Cup final, is on for Etienne Capoue. I don't see any similar late heroics happening from him this time...
Just as I write that, City come forward again and Yaya Toure fizzes a shot a few inches wide. The home side are in complete control of this match now.
Safe to say that City don't look too bothered about extending their lead. David Silva, who has been exceptional again this afternoon, is replaced by Fabian Delph.

Another change for Watford, Miguel Layun is on for Odion Ighalo.
Hang on, maybe this game isn't quite over yet. Troy Deeney's clever dummy gives Ikechi Anya space for a shot and it takes a smart block from City defender Bacary Sagna to divert the ball to safety.
Sebastien Prodl takes out City striker Sergio Aguero and quickly finds himself in the book.
A first change for Watford. Ikechi Anya is on for Almen Abdi. A big ask for him to change the direction of this game though.
The Hornets have no choice but to get forward now but they are leaving gaping holes behind them when they do. City break and Bacary Sagna would be in if Raheem Sterling had got the correct weight on his pass.
It's still early days, of course... and this game is not over yet... but things are looking very good indeed for Manchester City right now...Copyright: .
Man City are not finished yet by the looks of things. This time Raheem Sterling turns provider, with a low cross from the right, but Sergio Aguero slips as he tries to turn it home and scuffs his shot horribly.
Well, Watford do open up... but not in the way they would have wanted. After Yaya Toure's free-kick is charged down, David Silva plays a precise pass to Fernandinho, running into the area down the right... and his bullet finish flies into the opposite corner of the net.Copyright: AP
Hmmm, not much of a response from Watford so far. Troy Deeney has pushed up a bit but his team-mates are still sitting very deep - surely they will have to open up eventually.

"Watford switch off - it's far too easy for Sagna to get the ball in. Sterling makes a great run across the near post and it's a very deft finish."
This is the first time Watford have been behind this season. How will they react?
City changed their shape at the break with David Silva going wide right and Samir Nasri on the left. Raheem Sterling was pushed up front in the middle alongside Sergio Aguero - fair to say the switch paid off.

We have picked up where we left off before half-time. City have the ball and all of Watford's players are behind it.
City get the second half started
City are bringing on Samir Nasri for Jesus Navas for the second half. You can understand why - a case of more guile needed, less speed.
Former Wales striker on Final Score
"Watford have dug in. They've made themselves difficult to score against, and Quique Flores will be delighted. But Manchester City are probing and probing and you just feel eventually they will break them down."
Manchester City are getting plenty of men forward, Watford.... less so. As you can see by the average position of their touches.

There will be one minute of added time at the end of the first half. Watford have succeeded in their mission of killing the game, so far anyway...Copyright: EPA
Watford right-back Allan-Romeo Nyom joins Vincent Kompany in the referee's book after clattering Raheem Sterling.
When play restarts, City come forward down the right and Jesus Navas lets fly with a shot that goes out for a throw. That sort of sums up the first half for the home team in front of goal.
The pattern of this game has not changed - Watford frequently have 11 men behind the ball.
Their nominal lone striker, Troy Deeney, is helping his right-back Allan-Romeo Nyom out whenever City come forward down the left, tracking Aleksandar Kolarov's runs.
City skipper Vincent Kompany is the first player to go in Mark Clattenburg's book, for a late lunge on Jose Manuel Jurado. Watford's free-kick from 40 yards out fails to beat the first defender though.
Sergio Aguero has been kept relatively quiet so far, but springs into life when the ball reaches him on the edge of the Watford area. He turns to fire in a stinging shot but Heurelho Gomes watches it zip wide of his left-hand post.
In case you've just joined me, this game is all about City's attack vs Watford's defence... and the defence is on top at the moment.
The frustration continues for City - they have had 60% of possession, but have not been allowed to test Heurelho Gomes too often.Copyright: PA
The Hornets have not really threatened much at the other end, but that is always going to be tough when your striker is operating in a similar area to a defensive midfield player.
Almen Abdi has just curled in a cross from deep out on the right, but it was an easy catch for City keeper Joe Hart.
Just to reiterate - Watford are well organised and their game plan is working at the moment. City just cannot find the right pass to break them down.
City are keeping this spell of pressure up, but Watford have all their players back in their own half and behind the ball.
So far, so good for Watford.
City are finding a few cracks in the Hornets defence, though. Bacary Sagna brings a low save from Heurelho Gomes when a corner is not cleared and, soon after, Raheem Sterling brings another good stop from the keeper... with his low shot squeezing under the Brazilian who got just about enough on it to turn it the wrong side of the post. The ball trundled a couple of inches wide.
Here's the two teams' average positions (of their touches) so far. As you can see, Watford have spent most of the time in their own half...Copyright: Opta
A first real sight of goal for Manchester City when Watford give the ball away and it is fed to Raheem Sterling, running into the area down the left. His first goal for his new club? No, an excellent block by Craig Cathcart stops his shot from reaching the target.
Aleksandar Kolarov comes over to the right to fire in a free-kick, but curls it over the bar. Moments later he tries to bend another set-piece into the box from out wide on the left. Watford continue to hold out, though.Copyright: Getty Images
Man City have attacked mainly down the left so far, through Aleksandar Kolarov, Raheem Sterling and David Silva. No joy for them yet in terms of creating an opening.Copyright: BBC Opta
City, meanwhile have let the tempo drop and are not coming forward with any real purpose. They have just worked an opening for Jesus Navas, who was over on the left after taking a corner, but he horribly over-hit his cross.
Watford have grown into this game now, and are keeping the ball with a bit more confidence in the City half as well as their own.
When the corner comes in, it falls for Craig Cathcart, who sees his shot blocked by Bacary Sagna, and City are grateful to see the ball trickle wide. A couple more crosses come in from the visitors but City survive.
Better from Watford. Jole Holebas gets forward down the left and his cross is headed behind by Vincent Kompany. A first corner for the Hornets.
Watford are in the same basic 4-2-3-1 shape as City, just a lot deeper right now. The Hornets are doing OK when they spray passes around by the half-way line but they have not got anywhere near the City area yet.
City break quickly this time and Sergio Aguero does get a shot away after running at Craig Cathcart on the edge of the box. It is the first strike on goal of the game but is a tame effort, easily blocked by Cathcart's outstretched foot.
A neat build-up from City ends when Sergio Aguero is crowded out on the edge of the Watford area before he can get a shot away, but the Hornets are doing a lot of defending at the moment.Copyright: Getty Images
Watford have barely made it into the City half since kick-off but they manage a few neat passes here before Yaya Toure clatters into Almen Abdi, earning him a ticking-off from referee Mark Clattenburg. No card is shown but that looked like a final warning to me.
City come forward down the left again but Almen Abdi stops the ball from reaching Sergio Aguero inside the Watford area and goalkeeper Heurelho Gomes hoofs it clear.
Eliaquim Mangala can't get on the end of the corner when it is swung in but Watford fail to clear their lines. City have seen pretty much all of the ball so far.
Raheem Sterling and Aleksandar Kolarov link up well down the left as City mount their first attack, and force their first corner.
Watford get us going.
A few patches of blue in the sky above Etihad Stadium as we prepare to kick off... not many, though - we are talking 80% cloud cover.
Right then, the players are in the tunnel, so not long to go.
Out on the pitch are some City legends - Tony Book and Colin Bell are here to honour Mike Summerbee, who joined the Manchester club almost 50 years ago today.

MOTD pundit Danny Murphy has taken a look at Manchester City's attack this week - specifically the width offered by Raheem Sterling and Jesus Navas.
Murphy says: "They both keep defenders occupied and also offer a threat in behind defences with their pace. That creates panic, which you did not see when David Silva or Samir Nasri played wide last season.
"Sterling and Navas have given City pace and width that they did not previously have on both flanks, which in turn has given Silva more space in the centre of midfield.
Match of the Day commentator
"There seems no logical reason why this match should be anything other than a routine home win - doubtless the word "complacency" will be uttered around Etihad Stadium in order to guarantee the home side's focus is unwavering.
"However, it was this time last season when Manchester City first came unstuck in the defence of their title, losing unexpectedly at home to Stoke.
"Home draws against Burnley and Hull demonstrated last term that their glittering array of talent can be susceptible to a drop in intensity against so called "lesser" opposition.
"Like City, Watford are unbeaten and, having secured an excellent draw at Everton on the opening day, they appear to have sufficient stoicism to be competitive."
Watford boss Quique Sanchez Flores made 11 changes for the midweek Capital One defeat by Preston, and makes 10 this time as he reverts to the core of the team that drew 0-0 with Southampton last week. The only difference is that Almen Abdi is picked in midfield ahead of Ikechi Anya.

Manchester City stick with the same team that have started their last two Premier League games this season, and there is no place for £32m defender Nicholas Otamendi on the bench.

BBC Radio 5 live at King Power Stadium
Speaking of predictions, here is Lawro with his take on today's clash at Etihad Stadium...
Lawro says: "I am a fan of Watford boss Quique Flores but it is asking a lot for his team to get a fourth draw of the season against Manchester City.
"City's present system makes the pitch bigger, stretches play and allows David Silva more room to play in the middle - when that happens, it is a case of 'all the best' to the opposition."
