The back of every seat at Stamford Bridge now has instructions on how to report incidents of abuse as part of the club’s drive to stamp it out.
“Chelsea Football Club finds any form of discriminatory behaviour totally abhorrent. It has no place at Chelsea or in any of our communities,” said a Chelsea statement.
“Chelsea FC has consistently made its zero-tolerance position on discriminatory behaviour very clear, yet there are still idiots like this that attach themselves to this club as so-called ‘fans’, which shames Chelsea FC, our coaches, players, staff and our true supporters.
“We are investigating this incident and, if identified, this individual will face the strongest action from the club.”
