The scoreline was comfortable for the Germanâ€™s as was the performance in their eighth win in nine Champions League games on home soil.
The game was over by the break with two goals from Mario Gomez in quick succession taking his tally for the season to eleven strikes.
City had looked comfortable for the first 30 minutes but once the hostâ€™s opened the scoring Roberto Manciniâ€™s outfit had no answer to the swift attacking play of the Germanâ€™s and were given a reality check on the progress they have made.
Hart will feel aggrieved with both goals as he saved the initial efforts but was unlucky to beaten on the rebound, but in the second-half was frequently called upon to keep the scoreline respectable.
City may well be coasting in the Premiership but on the European stage they were sadly found lacking.
