Kolo Toure has instructed his agents to offer the Ivorian international’s services to Barcelona, according to Cadena Ser.Following several seasons in London with Arsenal, the defender jumped ship with team-mate Emmanuel Adebayor this past summer; making a €18 million move to Eastlands.Despite City’s big spending, things haven’t quite gone as planned for Mark Hughes so far this season and Toure is said to already be looking for a way out of the club.Kolo’s brother, Barcelona midfielder Yaya Toure, has constantly expressed his desire to play in the same team as his older sibling and the feeling seems like it's mutual.Having failed to entice Yaya to Arsenal or City, Kolo is apparently ready to make the move to Spain as soon as the winter transfer window. However, it is believed that the Citizens will be reluctant to sell.
