The 27-year-old midfielder was in Frankfurt on Tuesday to undergo a medical before finalising terms of his free transfer from Turkey.

He has agreed a two-year contract with the Bundesliga side, where he joins his compatriot Naohiro Takahara.

The former Arsenal, Fulham and West Bromwich Albion midfielder failed to make a name for himself in the Turkish Super Lig, playing just 25 times all last season.
