Carlos Tevez is left as an unused substitute as English side are unable to cope with the dominance of four-time Champions League winners and made to look toothless in Bavaria
The German striker scored twice within the last eight minutes of the first half to stun City who had competed in the early stages of a contest which Jupp Heynckes's side controlled once they were in front.
Four-time European champions, Bayern had won their previous nine games in a row conceding zero goals in the process and it showed as the English FA Cup winners had no real answer to the questions being asked of them.
City, in their first Champions League campaign, slip to third in Group A still looking for their first win in the competition.
The early period of the first half was an example of back and forth sparring from both sides. Mancini’s side had the better of the early exchanges and within three minutes City could have been awarded a penalty after a clumsy challenge from former City defender Jerome Boateng felled David Silva close to the byeline. The Hungarian officials were not moved and the Spaniard didn’t reinforce the claim with much protestations.
City continued to edge the even battle when a run from Micah Richards setup Edin Dzeko who’s recent form deserted him as his shot was direct at Manuel Neuer between the Bayern posts.
A free-kick from Yaya Toure tested Neuer from 30 yards but the opening was still to come as neither side could find a way through the stout defending on show.
The Munich fans were growing restless as a lack of chances is not what they’re used to and the collective mood was not improved when a Toni Kroos shot sailed high over Joe Hart when he could have passed to Gomez or Frank Ribery.
Bayern were now improving by the minute and Bastian Schweinsteiger could have opened the scoring on two occasions, the first was a result of nifty work with Ribery which ended unluckily and the second was a simple horrendous miss. Bayern caught City in possession and quick as a flash, Thomas Muller’s efforts allowed him to stroke the ball to Schweinsteiger who, from seven yards, spooned it.
Such a miss from an experienced international was shocking and Heynckes on the Bayern bench was livid with what he was witnessing.
His mood improved within sixty seconds when Bayern finally opened the scoring after Ribery’s long range shot was well saved by Joe Hart only to see Muller pounce on the rebound, but Hart was up to the challenge and an excellent reflex save denied Muller; but that’s where Hart’s luck ran out. Gomez smashed the ball home on the second rebound and Bayern took a deserved lead after controlling the latter part of the half.
With Hart screaming at his errant defence, he was under the cosh almost immediately again when more poor City defending allowed Gomez to drift to the near post from a Muller free kick and head the second goal of the game. Television replays showed that Gomez was offside but the goal stood and Mancini’s men were learning the hard way what the Champions League was all about.
Once the second half begun it appeared that City had run out of ideas. The team which put five past Tottenham and were still unbeaten in domestic football were not in attendance and some interesting substitutions from Mancini further reduced the chances of a comeback. After 55 minutes the effective Edin Dzeko was replaced by Nigel de Jong and the Bosnian was furious to be removed from action and he made sure that his manager was aware of this as dissention was rife on the City bench with Carlos Tevez joining in the arguments.
With Tevez on the bench the decision to bring on Alexsander Kolarov and James Milner was an odd move as City were searching for a way back into the game.
After two games City have one point and qualification for the next stage is looking a bigger task than many thought it would be.
