Chelsea defender Toni Rudiger is demanding greater action from UEFA against racist chants at stadiums across Europe.

Rudiger was the subject of racist abuse against former club AS Roma in the Champions League last season.

"They have to do more," he told BBC Sport.

"If they do not act against it anymore, they will do the same as people who are guilty of racism.

"Maybe they think it's hard to punish the fans, but for me it means a clear signal that they accept it (racism)."
