City and Bayern fans will make a joint protest against UEFA just before kick off at Tuesday's Champions League showdown. Both groups of supporters are upset at their treatment by the governing body at their away fixtures with CSKA Moscow.
After many fans had booked hotels and flights UEFA announced the games in the Russian capital would be behind closed doors due to the behaviour of Moscow supporters.
UEFA have since ignored calls for the fans to be compensated. Matters were also made worse when City took to the pitch in Moscow with several hundred home fans cheering on the home side.
City's 1894 Group and Bayern's Club Nr.12 will protest by turning their backs and booing or whistling through the UEFA anthem.
