Chelsea star Antonio Rudiger says "racism has won" and that he had been made a "scapegoat" after Tottenham Hotspur and London police said they found no evidence to back his allegation he was abused during a Premier League match in December.
Rudiger was involved in an incident in which Tottenham's Son Heung-min was shown a red card and indicated shortly afterwards that he had been the victim of monkey chants from the home section of the crowd.
Referee Anthony Taylor halted play when Rudiger complained of hearing monkey noises from spectators. Shortly after the stoppage, an announcement made over the public address system warned that "racist behaviour among spectators is interfering with the game" and Taylor spoke to Tottenham manager Jose Mourinho and Chelsea counterpart Frank Lampard.
Two further public address announcements followed after play was resumed. However, Spurs and the Metropolitan Police said they had found no evidence of racial abuse.
"Racism has won. The offenders can always come back to the stadium, which shows these people have won," Sky Sports quoted Rudiger as saying.
Rudiger was subjected to jeers from some Tottenham fans during the match at Stamford Bridge.
"They never get punished and in the end, I'm the scapegoat. I won't give up, I'll never stop raising my voice. I'll always raise my voice, but in relation to this, I'm alone," he said.
"It's a disaster. I became a father last Thursday and you start thinking society hasn't come far enough in fighting racism so my kids will probably suffer as well.
"If nothing changes, if kids don't get good education and parenting, we'll lose."
The Professional Footballers' Association called for a government inquiry into racism within football in the wake of the incident.
The PFA said in a statement: "We are disgusted and dismayed that once again, a Premier League fixture has been tainted by abuse from the stands towards players.
"It has become clear that football players are on the receiving end of the blatant racism that is currently rife in the UK, but they are not alone.
"Racist abuse in football is not just an issue for black and ethnic minority players, it is an issue for everyone who loves the game.
"The PFA calls for a government inquiry into racism and the rise in hate crime within football."
