Aaron Broderick says: "They won't win the Europa League either! But it's funny to see both Manchester teams out of the Champions League."
Tom Stoddart says: "Man City deserved this game against Bayern. Shame about Napoli! Blues definitely going out in style!"
Mancini's squad went into Matchday Six with the odds stacked against them and, although they defeated the Bundesliga leaders, Napoli's win at Villarreal condemned them to Europa League football in 2012. Stay with us for all the post-match reaction.
City defeat Bayern Munich 2-0 at the Etihad Stadium, but they are made to pay for mistakes earlier in their European campaign as they are eliminated from the Champions League.
Johnson has the chance to make it three for City, but, in acres of space when eight yards from goal, he pulls his shot well wide.
Barry, De Jong and Nasri ping a few first-time passes among themselves. Both sides want the final whistle.
Bayern are finishing the stronger. City have known their Champions League dream is over for a quarter-of-an-hour.
Gustavo manages to dig out a cross at the byline. But Clichy can head clear when unchallenged at the back post.
Silva is heading off and is replaced by Adam Johnson. City are now thinking ahead to next Monday's Premier League trip to Chelsea.
It is still 2-0 to Napoli against Villarreal. City are going to be finishing third in Group A unless there is a remarkable turnaround.
City use the break in play to send on Balotteli in place of Y.Toure. Bayern send on Usami as a replacement for Petersen.
Y.Toure is still piling forward at every chance. But Aguero elects to play the pass to Nasri, who fires just wide.
Aguero bursts into life inside the Bayern box and almost collects a through ball. But Butt is off his line to dive at the feet of the Argentine.
Dzeko goes off and is replaced by De Jong. Mancini also made this change at the Allianz, which went on to spark the Carlos Tevez saga.
Calmly done by Savic, who knocks a cross back for Hart to collect. There is an almost pre-season feeling to this match since Napoli scored.
Tymoshchuk has the chance to move forward from midfield and set his sights from 25 yards. But it is catching practice for Hart and the City goalkeeper is behind the effort all the way.
Bayern are still struggling to make any sort of dent in the City defence. Rafinha crosses from the byline, but City can let Savic clear.
Savic has the chance to cross on the run when down the right. But the full-back makes a dreadful mess of things and hits the ball behind the goal.
The game is limping along at the moment. Both sides are allowing each other to have the ball in the midfield.
Bayern really have lived down to expectations this evening. Heynckes' team have not really looked interested in offering any sort of attacking threat.
Gokhan Inler scored Napoli's goal, but City are not letting the news from elsewhere impact upon their job. They are still going about their business.
But fists away a first-time effort from Barry from 25 yards. There have been a few groans around the stadium. The City fans must know Napoli are winning.
With that goal for Napoli, City are now heading for the Europa League. It does not matter what happens against Bayern, if Napoli win.
Rafinha skips past Clichy and manages to get a cross in from the right. City half clear the cross and Hart has to be alert to save Alaba's awkward, dipping volley.
City are struggling to get a touch as Bayern pass the ball about. But the visitors are going backwards.
City are passing the ball in sharp triangles. Y.Toure is looking to break from midfield at every opportunity.
Depending upon the amount of injury-time, it looks like the game in Spain will finish before this match. They kicked off for the second half about a minute before the Etihad Stadium game.
Bayern are possibly getting ready to send on the artillery. Gomez and Ribery are warming up on the touchline.
Pranjic wastes another chance to shoot. The changes in Bayern's team today have been very evident. They have lacked any momentum.
Clichy has the chance to cross on the run down the left. But he horribly over hits the cross and City's attack breaks down. There is more goals in this for Mancini's men. Napoli are still only drawing at Villarreal.
It is a superb goal from City. Y.Toure exchanged passes with Silva before doing likewise with Dzeko on the edge of the box before darting onto the ball and poking it past Butt. City fans erupt into the 'Poznan'.
Nasri has been guilty of giving the ball away on several occasions tonight and again he gifts the play to Tymoshchuk.
City make a lot of hassle out of attempting to clear the ball from Rafinha. It is the unlikely figure of Silva who eventually comes back to tidy up.
City have clearly been told not to give Bayern any time on the ball. Tymoshchuk is closed down by three City players and gives away a throw-in.
Silva collects a long pass and cleverly taps the ball into the path of Dzeko. But, under pressure, Dzeko hits a shot over the bar.
After some patient build-up, Pranjic tries his luck from 20 yards. He drags his shot wide of the near post.
Rafinha attacks down the right, but Bayern are just looking to keep hold of the ball at the start of this half.
WE'RE BACK: Bayern get the second half under way. They have not sent on anyone from their ominous substitutes.
Tom Stoddart says: "City will hopefully keep the lead! Aguero to grab a late goal to seal the win!!"
Bayern have looked totally disinterested. I think there are more goals in this for City. Mancini and his club just need Villarreal to hang on or take the lead against Napoli.
Sky Bet say: "Manchester City lead Bayern 1-0 at the interval and are 1/8 to seal victory. A draw is 6/1 and the visitors are 25/1 to come back and win."
Silva's wonderful goal is the difference between the teams. The good news for City is that Napoli are also failing to win. They are drawing 0-0 with Villarreal. As it stands, City will qualify for the knockout stages. Let me have your thoughts on the first half at email@example.com or via twitter @SkySportsPeteF.
Bayern fail to completely clear the corner and Aguero ends up sending a curling shot just wide of the far post from 16 yards.
Clichy telegraphs a cross-field pass and can run forward with the ball. Savic is then released down the right and he wins a corner.
Lescott intercepts a pass forward from Boateng and City immediately spring into attack. Dzeko has the ball, but his touch is heavy and Bayern can regain possession.
Aguero darts forward and beats a couple of Bayern defenders before beating Butt with the eyes and rolling a shot goalwards. Boateng, though, is back to slide a clearance and prevent City from taking a two-goal lead.
It will be interesting to see if Bayern now show any more attacking intent after falling behind. Rafina charges forward, but the move breaks down.
What a response from Silva who had looked in some pain after being fouled. He collected a flick on from Dzeko to rifle an unerring half-volley past Butt from the edge of the box. As it stands with Napoli drawing, City are qualifying in second place in Group A.
Throw-in to City and Savic looks to take it quickly. But none of his team-mates are switched on and the fans groan.
This looks like it is going to be a frustrating night for City. The home team are dominating, but are really struggling to create any chances.
Ironic cheers around the stadium as Boateng fouls Dzeko wide on the right. A chance for City to cross. But Nasri's free-kick is headed clear by Petersen.
Contento loses possession in his own half and then brings down Dzeko. Free-kick to City, which goes back to defence.
Olic looks to turn past Kompany close to City's corner flag. The City captain, though, is too strong and defends immaculately.
Butt punches, again, when under pressure from Lescott. Nasri's follow-up from 20 yards is straight at the Bayern goalkeeper.
Barry threads a pass between midfielders towards Aguero. A cross eventually finds Dzeko, but he cannot get a meaningful touch and City win a corner.
The set-piece is again a let-down and Bayern are content just to keep hold of the ball inside City's half.
City win a corner and the chance to put Butt under pressure in the air, again. The goalkeeper punches away Silva's set-piece.
There is a bit of a flat atmosphere at the Etihad. There has been little to get excited about so far.
Nasri twists and turns brilliantly before poking a ball forward towards Aguero. The Argentine hits the accelerator, however, Butt is quickly off his line to clear the danger.
The pattern of the match is continuing. City are dominating the ball, however, Bayern are remaining very cautious, well organised and difficult to break down.
Nasri robs Gustavo of possession in midfield and then gets the ball back from Silva. Nasri goes for glory from 20 yards, but drags his shot well wide.
City are suddenly in a mess at the back. Tymoshchuk's shot deflects, but a combination of Olic and Luiz Gustavo cannot capitalise as the ball loops out of play.
Silva swings in the free-kick and Lescott thinks he has scored. But a foul is awarded against the centre-back for his aerial challenge with Butt. The Bayern goalkeeper was not convincing, but you never get away with colliding with a shot-stopper in Europe.
Savic leads an attack down the right and Olic is guilty of a cynical trip on the full-back. Booking.
Nasri is floating around the space between midfield and attack. He plays a ball forward to Dzeko, but Bayern are back in numbers.
Bayern move up field from the free-kick and Olic tests Hart from 18 yards. Hart has to push the shot behind for a corner, which City comfortably survive.
Nasri lobs the free-kick into the Bayern box, but Dzeko is either offside or guilty of pushing and it is a free-kick to Bayern.
David Alaba looks to start a Bayern attack, but gives the ball straight to Barry. City move forward and Y.Toure is fouled by Tymoshchuk.
Dzeko looks to play a give-and-go with Silva. But Silva's return pass has a bit too much on it and Dzeko gives away a foul inside the Bayern box when attempting to regain possession.
Olic, who could leave Bayern in January given his limited first-team opportunities, is back on the pitch and is moving okay.
Savic challenges for an aerial ball with Olic and the City defender lands on the Bayern forward's ankle. Ouch.
Nasri bursts down the right, lifts his head and crosses. Aguero comes in on the blindside with a well-timed run, but heads high over the bar. That was a waste from the Argentine.
All a bit of a scrappy start, with lots of throw-ins disrupting the flow of the match in the very early stages.
Bayern are happy to give the City defence the ball and are dropping off to the half-way line. Y.Toure looks to start an attack.
Aguero goes close to blocking a back-pass to Butt. Bayern are taking a few chances when passing it around at the back.
Savic is attacking in the early stages and is brought down in the Bayern half for a free-kick to City.
Nasri is immediately on the attack, but it is a throw-in to Bayern. Diego Contento takes the throw-in.
The Champions League anthem booms around the stadium. Will that be the last time City hear that tune this season?
Here come the teams. Kompany leads out City, while Butt is Bayern's captain tonight amid the much-changed side, which has been hit by a bout of the flu.
Tonight's referee is Frenchman Stephane Lannoy. According to UEFA's press pack, he is 'particularly regarded for his physical fitness and ability to communicate with players'.
Speaking of having a flutter, Sky Bet say: "Manchester City (8/15) need a win tonight to have any hope of progressing and have to hope results go their way. Bayern are 5/1 to win, with a draw available at 3/1."
Liam Ferguson says: "I have 2 bets on, 2-0 and 2-1 to Man City with Balotelli to score first, not really happy with him starting on the bench."
Mancini has just said on TV regarding the sniping comments of Bayern CEO Karl-Heinz Rummenigge about City: "After the game, if he is here, I want to ask him why."
Jerome Boateng will, of course, be one to watch this evening. The former City player will want to knock out his ex-club after a disappointing spell in England. His old sparring partner, Balotelli, is on the bench.
Sami Tumarevic says: "I think Man City will take control in the first half and score. By half-time it will probably be at least 1 - 1. But I think City have got a big chance of winning, and hoping Napoli will lose!"
City will be happy Mario Gomez is only on the Bayern bench. The striker scored twice at the Allianz Arena and is the Champions League's joint top scorer alongside Lionel Messi this season with six goals.
Are City fans happy Mario Balotelli is beginning the match as a substitute? The Italian will be suspended in UEFA competition if he incurs one more booking.
Steven Doyle says: "Man City to win 3-1, Villarreal v Napoli 2-2. Man City go through. You heard it here first."
Steven Broadbent says: "Have a feeling Villarreal will do City a favour but City will struggle to take it. 2-2 is my bet."
Matt, I'll agree with you that every club assembles a squad to a degree of expense. But at no point do I insinuate City should be winning every game.
Matt Stafford in Buenos Aires says: "Why oh why do you and so many other pundits have to use the pre-match phrase "Roberto Mancini's expensively assembled squad"? As a Man City fan I'm really tired of hearing that same overused phrase that tries to insinuate that because we've been forced to pay over the odds for players to put a decent team together, we should be favourites and winning every game. Is Bayern Munich not also an expensively assembled squad? How much would it cost for the likes of newly-rich clubs like QPR or Paris Saint-Germain buy the individual players of the Bayern squad? Now that we've firmly established ourselves as a top four club and hopefully playing in the Champions League on a regular basis, we won't need to pay those over-inflated prices to attract players, so does that mean that the media will stop using that phrase with City?"
Where have City gone wrong in the Champions League to leave them facing such a difficult situation in their final match? What have been the turning points?
Cian Hughes says: "Really tough game. I really want City to qualify. Bayern are doing brilliant in their league and so our City! Tough decision. I will go for a 2-1 win for City with: Aguero+Dzeko."
Lots of changes for Bayern, unsurprisingly, City - who have included Stefan Savic amid their injury problems at full-back - have surely got to fancy their chances against this team. But I fear for Mancini that Napoli will win at Villarreal, rendering this match at the Etihad as a meaningless game. What do you reckon? Get in touch at firstname.lastname@example.org or via twitter @SkySportsPeteF.
Bayern team: Butt, Rafinha, Boateng, Contento, Badstuber, Pranjic, Alaba, Luiz Gustavo, Tymoshchuk, Petersen, Olic. Subs: Neuer, Van Buyten, Lahm, Ribery, Usami, Muller, Gomez.
Manchester City team: Hart, Kompany, Lescott, Savic, Clichy, Barry, Nasri, Y.Toure, Dzeko, Silva, Aguero. Subs: Pantilimon, Zabaleta, K.Toure, Milner, A.Johnson, De Jong, Balotelli.
Bayern, though, are not the same force which administered and educating defeat on City in Germany on Matchday Two. Since that win at the Allianz Arena, Jupp Heynckes' team have drawn two and lost three out of 12 games in all competitions. They are also set to name a much changed team, with the likes of Bastian Schweinsteiger, Arjen Robben and Toni Kroos all missing through injury or illness while Thomas Muller and Mario Gomez are also doubts.
City can take heart from a 14-match unbeaten run at home in Europe. But Bayern arrive with six wins from their last eight in the Champions League. Bayern's last visit to England also included the elimination of Mancunian hosts, with Manchester United being knocked out in the 2009/10 quarter-finals.
As we await the team news, I cannot help but feel a sense of disappointment about City's Champions League campaign. It has always seemed as if they have had other priorities, which is a shame given the euphoria which surrounded the Etihad Stadium on Matchday One. What do you think? Drop me a line with your thoughts on this and any other issue throughout the evening at email@example.com or via twitter @SkySportsPeteF and I will publish the best comments.
It is boom or bust for City. Defeat to Napoli last time out means Roberto Mancini's expensively-assembled squad after to defeat Bayern, who are already confirmed as group winners, and hope the Serie A club drop points at Villarreal.
