Tottenham say investigation into alleged racial abuse of Chelsea defender Antonio Rudiger is so far ‘inconclusive’

The Blues defender indicated to both his captain Cesar Azpilicueta and referee Anthony Taylor that monkey chants were being directed at him.

The alleged abuse start soon after Heung-min Son was sent off for a kick out at Rudiger.

Soon after the defender reported the abuse, Taylor implemented the first step of FIFA’s protocol in dealing with discrimination in games – with a stadium announcement stating that ‘racist behaviour is interfering with the game’.

Two further calls from the stadium PA came before the end of the contest, which Chelsea won 2-0.

Tottenham released a statement on Monday vowing to ‘exhaustively’ investigate the matter involving Rudiger.
