Manchester City are waiting to learn whether their Champions League group match at CSKA Moscow will have to be played behind closed doors.
UEFA is due to rule on Friday after CSKA were charged over the alleged poor behaviour of their fans.
A number of incidents occurred during CSKA's opening Group E match at Roma, which the Russian side lost 5-1, last month.
Flares were thrown onto the pitch, scuffles broke out in the stands and a banner containing a racial slur was also unfurled.
CSKA have already been punished twice over incidences of racism by UEFA in the past year.
Last year's Champions League clash against City at the Khimki Arena was overshadowed by racist chanting aimed at Yaya Toure.
They were hit with a partial stadium closure but a repeat offence led to Tuesday's game against Bayern Munich being played behind closed doors.
Such a scenario being repeated for City's next visit on October 21 is a possibility as UEFA's control, ethics and disciplinary body convenes on Friday afternoon.
City manager Manuel Pellegrini feels it is a shame the matter may have come to this.
The Chilean said: "My personal thinking is football should always be with fans. I don't think it is good to play in an empty stadium, not good for anyone.
"I understand a local team have a little (problem) with their fans but all the people deserve to go to the stadium. I don't know what will happen."
A stadium closure could have implications for City supporters planning to travel but the club themselves have not sold any tickets or official packages for the fixture.
