Manchester City will write to UEFA regarding the CSKA Moscow fans who were allowed to attend Tuesday's Champions League match.
CSKA were forbidden from selling tickets for the Group E clash but 200 to 300 home supporters made it into the Arena Khimki for the 2-2 draw while the end where Manchester City fans would be seated remained empty.
Captain Vincent Kompany voiced his disapproval after the game and Press Association Sport understands City will contact Europe's governing body to make clear their disappointment on behalf of the club's fans.
Kompany said: ''You say 'no fans' then all of a sudden you turn up and basically the only team that hasn't got fans is Man City. So who's getting punished? Who is being done for racism? Man City or Moscow?''
UEFA chief of press Pedro Pinto insisted the 'supporters' were guests of sponsors, staff or parents of ball boys who are not covered by the stadium ban.
''The game was still played behind closed doors," Pinto said.
"We have sponsors that get tickets to every game even when sanctions are involved, as do staff and the parents of the ball boys, and that was the situation yesterday.
''As far as the corporate guests are concerned we cannot control what they wear or if they take scarves or flags but there was no inappropriate behaviour or banners.
''Less than three per cent of the stadium was used and the club do not get gate receipts and enjoy the product that is the Champions League - they were still penalised.''
UEFA president Michel Platini will put forward a plan to allow only women and children into European matches as punishment for racist behaviour.
The proposal will be up for discussion by European football's chiefs after a successful use of the scheme in Turkey in 2011, where Fenerbahce imposed the rule after a series of hooliganism incidents.
Pinto told Press Association Sport: ''The president has suggested an idea where instead of having empty stadiums only women and children are allowed into the match.
''This is just an idea at this stage but Mr Platini is open to discussing it inside UEFA to see if it is better overall for fans and for the image of football.
''The women and children would not have to pay for tickets so the club would still incur a financial penalty.
''This system was used in Turkey to deal with unruly behaviour by fans with great success.''
Meanwhile, UEFA has charged BATE Borisov with racist behaviour of fans towards Shakhtar Donetsk player Luis Adriano, which saw the referee suspend the game.
The Belarus club has issued an apology for their fans' ''shameful'' behaviour.
It said: ''We consider such behaviour to be completely barbaric and idiotic. We hope that it will never be repeated in our stadium.''
