The 17-year-old striker claims to have witnessed several incidents in which racial slurs are alleged to have been used.
Spartak captain Leonid Mironov is the player accused of that abuse, but he denies the allegations and Brewster is waiting to find out a date for a UEFA disciplinary hearing.
"Everyone stands behind the anti-racism banners". Idols of the game take part - but it still happens. It should have been more severe - a whole stadium ban.
"I jumped to my feet and the ref came running over because obviously he realised something had been said".

In a statement released last night, the FA said: "We take such matters extremely seriously and have worked to provide support to our young players should they be the victims of such abhorrent behaviour while representing club or country. That is how it feels anyway, like it has been brushed under the carpet", the teenager told The Guardian. "I want to be by myself and left to think". The next day I'll still be thinking about it.Under UEFA's rules any player found guilty of making racial slurs can be suspended for a minimum of 10 matches.
"I am really long in the business, in the sport, and I never faced a situation like that".
"I'm really happy - and he needed to be - that he is fearless enough to do what he did, it's such an important thing".
"A lot of people think it doesn't happen but obviously it does all the time". It's such an important thing. "I can not believe that people still have these thoughts in their mind".
"It's so unusual that it happens in this world now, and we need a 17-year-old boy to shout out and say it is still happening all the time and that we need help to stop it. I told Steven (Gerrard, coach) what had happened and we made a complaint there".
