Anti-racism campaigner Lord Herman Ouseley has told ESPN that the John Terry case cannot reach "closure" until the "hurt, abuse and broken relationships" are addressed by the English football authorities.

On Thursday, Chelsea captain Terry confirmed he will not appeal against the sanctions imposed by the Football Association after he was found guilty of racially abusing Anton Ferdinand last year.
Terry, 31, was given a four-match ban and a £220,000 fine after an FA panel found him guilty of insulting the Queens Park Rangers defender during a game at Loftus Road last October.
Lord Ouseley, chairman of Kick It Out, is calling for a full scale review of the process, while he is also seeking an explanation of Chelsea's stance during the last 12 months and the reason for England manager Roy Hodgson's public praise for the defender.
He told ESPN: "First of all, I should say that we do welcome the apology from John Terry and we welcome the apology from his club Chelsea, and we hope that can provide a basis for all the outstanding ongoing concerns to be resolved, but before we can bring closure to this there are many questions that need answers. There is the question of the FA hearing talking about collusion and cover-ups.
"There is the question of fractured relationships between people over the past 12 months, the question of why it has taken so long, why it has been allowed to cause so much hurt and abuse to the Ferdinand family.
"There is the question of what the FA and the PFA intend to do about all these issues going forward. I certainly want to hear more from Chelsea. Their actions have been confidential. That isn't good enough.
"We deserve to know what they have done. They have backed him all the way through, and said he is innocent until proven guilty. Chelsea want to move on, they say - I am sure that they do, but there are big issues still to be resolved about people's bruised feelings, the hurt that has been caused and how that can be repaired.
"We are continually asked whether a four-game ban is enough. I don't intend to comment on that, but we do need to address with the FA and the PFA the issues of the [Liverpool] players who wore T-shirts for the Wigan game backing Luis Suarez, we need to hear from the FA about Roy Hodgson saying how wonderful John Terry is as a person.
"The FA cannot just attack Serbia for racial abuse - they have to tackle these issues here as well. I am not seeking retribution, far from it, I am not a vindictive man, and that is not the point - we have to see how all of this moves the game in the right direction."
