Chelsea and England midfielder Ruben Loftus-Cheek praised his international team-mate Raheem Sterling for being strong-willed enough to speak out publicly against the racist abuse he has received.
Television cameras caught a Chelsea fan allegedly aiming racist abuse at Sterling during the Blues' 2-0 win over City at Stamford Bridge on Saturday.
Chelsea and the British police are investigating the incident. The club have suspended four fans until they have concluded their probe, with the threat of permanent bans if they find evidence of racist behaviour.
Loftus-Cheek and Sterling were part of England's squad that reached the semi-finals of the World Cup in July.
"I haven't spoken to Raheem about it. I prefer to leave him and let him deal with it mentally himself," said Loftus-Cheek on Wednesday ahead of Chelsea's Europa League tie in Hungary against Vidi.
"He's a strong-minded person so I'm sure he will be alright but I think he was right to say what he said.
"I don't think it should be in the game, or anywhere, so him speaking out was the right thing to do and if it happened to me I would do the same."
