Why i left trabzonspor mikel

I think there may be some confusion here!

Mikel John Obi is a Nigerian professional footballer who has played for several clubs, including Chelsea, Middlesbrough, and Tianjin TEDA. However, I couldn't find any information about him playing for Trabzonspor.

Trabzonspor is a Turkish football club based in Trabzon, and while they have had many international players throughout their history, Mikel John Obi is not one of them.
