Chelsea have condemned racist abuse directed at John Obi Mikel on Twitter, after the midfielder deleted his account.
The 25-year-old Nigerian removed his account 'Mikel12Official' from the social networking site less than 24 hours after his mistake helped cost the Blues victory in the opening Champions League match against Juventus.
Chelsea said they have informed police about the racist tweets.
A club statement read: "We've been made aware of racist tweets targeted at Mikel which are totally unacceptable, disgusting and abhorrent. We've informed the police and support taking the strongest possible action."
