Manchester City is on the brink of a third Champions League group phase elimination in four seasons ahead of Bayern Munich's visit to Etihad Stadium on Tuesday.

City's dismal 2-1 loss at home to CSKA Moscow in its previous outing left it at the bottom of Group E with only two points and it will be knocked out if it fails to beat Bayern and there is a winner in the Russian champion's home game with Roma.

Manuel Pellegrini's side can draw some solace from the fact Bayern, which shaded September's reverse fixture 1-0 thanks to a last-minute goal by former City player Jerome Boateng, is already guaranteed to qualify as group winner.
