Ceyhun Gulselam has completed his move from the Super Lig to the Bundesliga as he joins Hannover on a free transfer.
The Turkish international was born in Germany but has represented Turkey at both youth and senior levels.
"With Ceyhun Gulselam we have undertaken for the six [defensive midfield] position a player who brings the experience of over 100 top-flight games in Turkey," Sky Sports News quotes Hannover's sporting director Dirk Dufner as saying.
The defensive-minded midfielder can also fill in at centre-half if needed as cover.
