Chelsea's Antonio Rudiger was the target of racist abuse in the Blues' Champions League clash with Roma, according to European governing body Uefa who have opened disciplinary proceedings against the Italians.
Rudiger, a former Roma centre-back who Chelsea purchased for £35m this summer, is said to have been subjected to monkey chants by fans of his old team at Stamford Bridge during a 3-3 draw.
The Serie A side have now been charged with racist behaviour, with the case to be heard by the Uefa Control, Ethics and Disciplinary Body on 16 November.
"Disciplinary proceedings have been opened following the Uefa Champions League group stage match between Chelsea and AS Roma (3-3), played on 18 October in England," said Uefa in a statement.
"Charges against AS Roma: - Racist behaviour (monkey chants) - Art. 14 of the Disciplinary Regulations. This case will be dealt with by the Uefa Control, Ethics and Disciplinary Body on 16 November."
Roma have been fined for similar offences before. In 2013 they were hit with a paltry €50,000 (£45,000) fine by the Italian Football Association after three AC Milan players were abused by their fans.
In recent months Uefa have ordered Partizan Belgrade and Hajduk Split to play games behind closed doors after their fans were found to engaged in racist behaviour.
