The German-born Ghanaian defender has a future at Arminia Bielefeld and will not be loaned in the club’s overhauling process
The former Bundesliga campaigners are trimming down their squad size for next season to avoid redundancy.
“The current squad is too large, some players are hardly or only have very little chance of the seasons in the Second Division,” Kramer told lz.de
“Marcel Appiah will be kept as our first-choice right-back but with respect to Sebastian Glasner we will not put any impediment on his way if any club comes for his signature.”
He added: “Jonas Strifler, Dennis Riemer, Philip Heitholter Erdogan Yesilyurt, and others will also leave.”
The 25-year-old defender, was born in the German city of Schwelm to a Ghanaian father and an Italian father, gained promotion to the Arminia Bielefeld senior team in 2010 and has so far played 70 games scoring five times.
Appiah who can operate as a central defender is eligible to play for Ghana, Italy and Germany at the senior level.
