Supports: Kick It Out
Elliott retired early from professional football after damaging knee ligaments playing for Chelsea in 1992. Since then, he has become an ambassador for the Kick It Out campaign, the initiative to combat racism in football.
The campaign is holding two separate weeks of action from 16 and 28 October to reinforce its message of equality at football grounds across the UK.
"I represented the first and second generation of black players in the English game, when racism was at its ugliest in the UK," says Elliott. "I felt I could give something back by using my own experience as a player in that context. We have to keep feeding people positive messages."
