Kick It Out chairman Lord Herman Ouseley hopes John Terry's acquittal does not dissuade footballers from coming forward if they think they have been racially abused.
Chelsea skipper Terry was accused of making racist comments towards QPR defender Anton Ferdinand during a contest between the two sides in October last year.
But the 31-year-old, who says the racial terms he used were part of a sarcastic response to Ferdinand's accusation of abuse, was found not guilty by Westminster Magistrates' Court on Friday afternoon.
Ouseley, however, says the incident shows that much must still be done if racism is to be eradicated from English football and encouraged the Football Association to ensure they investigate claims of abuse to their fullest.
He told Sky Sports News: "We know that players are reluctant to come forward and raise this issue as it impacts on their own performance on the field and their relationship with the club.
"I don't think a situation in which people are not given greater confidence is going to help that and we've got to work hard to establish credibility in the complaints system and ensure they are dealt with properly.
"Racism exists in our society and in football and we at Kick It Out are working collectively with fans, managers, players and clubs in order to try and tackle this. The vast majority of people behave well but it seems like there is a problem with some players behaving in a way that is totally unacceptable.
"I'm glad it's over for both John Terry and Anton Ferdinand but I think the FA has to carry out its own investigations and conclude its deliberations, irrespective of whether the police get involved. They need to work with the clubs and ensure these things don't happen in the future.
"The vast majority of people who play football are appalled by [the words that were uttered in this case] and so are people who have no relationship with football.
"The situation has got better but inevitably when these incidents come out in the open they reveal what happens on a football pitch and at the highest level of football it has got to stop. [Players] influence their fans and are highly supported and they have to look at themselves and their conduct."
