Champions League winning midfielder John Obi Mikel has joined Middlesbrough on a short term deal.
The former Chelsea man, 31, was a free agent following the end of his deal with Chinese Super League side Tianjin TEDA.
While reports had linked him to European giants AS Roma and Wolfsburg, Mikel was was keen to return to the U.K. where his family remained during his two year stint in China.
Boro boss Tony Pulis said of the acquisition, the club's second in the January window after Rajiv van La Parra joined on loan from Huddersfield earlier in the month,
"I'm pleased to get him in. He is a man with a lot of experience and quality.
"He has a winning mentality and he wants to be here be a part of what we are looking to achieve."
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."
