Striker Diego Costa has praised the work of Chelsea's anti-discrimination campaign but says more has to be done to raise awareness on such a delicate issue.
The Spaniard's words come hours after a group of Chelsea football fans stopped a black man from boarding a train in Paris on Tuesday night, singing 'We're racist, we're racist and that's the way we like it'.
And the 26-year-old says people should stand up and fight for their rights.
"I know the club has been doing a lot of work in order to promote equality and take away discrimination," Costa told the club's official website.
"A lot of hard work has been done and it's hugely important.
"It's a delicate issue, not just racism, but discrimination as a whole, it doesn't matter about your social status or whether you have good or bad financial conditions.
"It's important we put a lot of work into it because the more people speak about these issues, the more chance there is of it getting out into the public domain.
"People that suffer from discrimination shouldn't stay quiet, because speaking about it will help them become stronger.
"As a community, as people, we must look at discrimination with real care, because people suffer from it unnecessarily and it's important we help one another."
