Tevez, who has been off the boil since coming on, springs to life and bursts forward on a menacing run, eventually earning a corner.
Silva has a vague penalty appeal turned down as we approach stoppage time, of which there'll be three minutes.
A mistake by Kompany allows Pandev in but Hart comes to his rescue by racing off his line to block an attempt on goal.
Dzemaili cuts inside on to his right foot and slices an effort into the stands, much to the frustration of his manager, who is animated on the touchline.
Aguero leads a City break following a Napoli corner and wins a free-kick. Meanwhile, Tevez comes on for Dzeko.
Johnson collects a return from a short corner and shoots towards the near-post, but De Sanctis is not to be fooled.
Finally, we have a score-line worthy of the play. It's been a great game and I've a feeling there's a winner in this either way.
Dzeko collects with his back to goal and, on the turn, he screws his shot wide. Great work by Johnson on the wing to create that chance.
Kolorav apparently had a broken nose when taking that free-kick, hence being withdrawn. City are on the ball now with the home support now full of life and urging them forward.
Goalscorer Kolarov is immediately replaced by Clichy while Nasri makes way for Johnson as City go all out for the win now.
City are level and it's a superb direct free-kick from Kolarov, who bends an effort over the wall and into the bottom corner with Napoli's keeper rooted to the spot.
Off the bar from Aguero, who steals in at the near post and flicks on only to see the woodwork deny City once more.
It was a fantastic goal by the way, great movement and great decision making, not to mention the flawless finish. Napoli break in search of a second but Hamsik drags an effort well wide of goal.
City regain possession and the atmosphere amongst the home support has gone a little flat, but the team need them right now.
Oh dear Gareth Barry, it's his attempted back-heel which allows Maggio to collect and stream forward and he feeds in a lovely weighted pass towards Cavani who slots it beneath the outrushing Hart.
The set-play comes to little and the hosts are back on the ball. Tevez is warming up on the touchline.
Hamsik collects out wide and shoots for goal, only being denied by a last-ditch lunge from Zabaleta. Napoli have a corner.
Dzemaili allows the ball to run across his body before he opens up and lets fly with a ferocious effort, which swerves away from goal at the last.
An hour has passed and it remains 0-0, but it's by no means a poor game here. You sense a moment of brilliance is going to settle it either way
A neat step-over from Dzeko creates space for a shot but the striker fires straight at Napoli's keeper.
Matthew Brown says: "City away to Munich right in the middle of the Oktoberfest, awesome." The perks of UCL football, eh?
Cannavaro wins an aerial battle with Aguero but almost turns it into his own net. From the corner, Lescott heads wide when well place to do at least hit the target.
Incredible goal-line clearance from Kompany as Napoli spring into life. A back-post pass finds Hamsik unmarked and the playmaker volleys on target, beating Hart but not the Belgian who boots clear from literally on the line.
Napoli's sturdy defence keeps City at bay once more as Barry is denied from close range by a last-ditch block.
City fan Trev says: "I think we should have played both Richards and Clichy for their attacking force, but i reckon we'll win 2-0 with Silva and Aguero on the sheet."
@BillzTucker says: "I believe City have a strong team but defence is weak so Lavezzi, Hamsik Cavani and Inler will pounce."
Cian Hughes loves a prediction, and tonight he's going for 3-0 to City with Aguero playing a starring role in the second-half.
@Scotty_91 has been impressed by City, saying: "At the moment by far the best team of the 45 minutes. Just need a goal."
@Aguero_90 says: "I expect a lot more from Lavezzi and Cavani, they are usually a lethal partnership who play off each other so well."

So, it's goalless at the break between Manchester City and Napoli. The Premier League side have edged the play, but both sides have struck the woodwork. The opening goal, if there is to be one, will be crucial no doubt.
Aguero cuts inside onto his right but, when well placed to cross, he opts to shoot and he does so way off target.
Aronica is the latest Napoli defender to go into the book for a late lunge on Aguro just outside the penalty area.
Yaya whacks a 40-yard free-kick but has the sting taken out of it before Aguero cleverly wins a corner.
Kolarov whips in the free-kick delivery and it bends in to short but bounces in front of the Napoli keeper, who is forces to punch clear.
The second is dealt with by City who break with Aguero leading the line, he cuts back across the face of goal and sets up Yaya, who thumps an effort against the crossbar!
Cannavaro holds up his hands - he knows he's late on Aguero and accepts his yellow card without complaint.
We're nearing the half-hour mark and it remains 0-0, but City have looked the more threatening side.
Silva picks up a loose ball and tries to place it in the far corner after one touch. He's foiled by an alert Napoli defence, though.
Cavani times his run to perfection but he can't quite control the lofted through ball and Hart allows the ball to roll out of play for a goal-kick.
Silva plays in Aguero but the Argentine cuts inside bringing Napoli's defence back into the play and they take advantage of that.
"Come on City" cry the home support in mass numbers, and it seems to have done the trick as the hosts emerge with possession and carry the ball up the opposite end.
Napoli find another sight of goal on the counter but Lavezzi shoots way off target this time from Cavani's tee-up.
First sight of goal for Napoli and it's that man Lavezzi, who opens up his body and bends an effort against the crossbar with Hart beaten, a warning for City!
The delivery is dealt with by Napoli - just. City continue the pressure from the resulting throw-in.
That last effort is the closest we've come to an opener. Meanwhile, Maggio goes into the book for halting Silva illegally.
Inler misplaces a pass and Kolarov intercepts it and ignites a counter-attack as Aguero waits for the overlap from Dzeko before the Bosnian fires a shot across the face of goal and wide.
Nasri's corner finds Dzeko unmarked and the striker glances on for Aguero, who can't beat De Sanctis at his near post.
Inler trips up Dzeko when trying to track back to help out his struggling defence. City are preparing to shoot from around 30 yards here.
Dzeko finds some space and opts to shoot from range, dragging a tame effort well wide from around 30 yards.
The corner is whipped in but neither Kompany nor Lescott can make contact and it sails out of play at the far end.
Yaya's pass to Aguero is a tad too strong and the Argentine is forced wide, but upon the delivery Dzeko tees up Nasri, who flashes a powerful half-volley wide.
City get the ball rolling in Manchester but the Italians immediately win possession from a throw-in.
Despite it being City's first UCL appearance, seven of their starting XI have experience in the competition. Kick-off is seconds away....
Chris Green's head says 2-2 but his heart says a City win: "It won't be easy for them at all as Napoli have some very powerful, talented and exciting players in their squad in the hands of Pandev, Hamsik, Lavezzi and Cavani."
Fancy a bet? After his hat-trick at the weekend Sergio Aguero is Sky Bet's joint-favourite to open the scoring along with Edin Dzeko. But if you fancy Napoli to score first, Ezequiel Lavezzi is a great price at 9/1.
With only one league fixture under their belt following a strike in Serie A, doubts surround Napoli's match fitness while City have been firing on all cylinders in the Premier League.
