"City can confirm we are in talks with Turkish club Fenerbahce regarding a deal to bring experienced Nigerian international central defender Joseph Yobo to Carrow Road on loan until the end of the season," said a statement on the club's official website.
"Yobo, 33, played for Standard Liege, Marseille, Tenerife and Everton before joining Fenerbahce in August 2010.
"Initially joining Everton on loan from Marseille, he made a total of 258 appearances in all competitions for the Toffees and scored 10 goals."
