The Colombia international is surplus to requirements at the Emirates following the arrival of £26m-man Bernd Leno, 25, from Bayer Leverkusen during the summer.
Ospina, 29, has long been linked with a move to Turkey after failing to nail-down the Gunners number one shirt since joining in 2014.
However, the former brother-in-law of James Rodriguez was never convincing in his 70 first-team appearances for Arsenal and found himself on the bench or seen as the club’s cup goalkeeper.
In the final year of his contract, Ospina is set to leave Arsenal for €5m, which is a pittance compared to the £12.5m fee Liverpool commanded for Danny Ward. It’s led to strong criticism of the club’s negotiators from some sections of the Arsenal fanbase.
New Gunners coach Unai Emery named Ospina, along with Carl Jenkinson and Joel Campbell, as players who will be leaving the club this summer.
None of those names comes as any surprise with Campbell spending six of his seven seasons as an Arsenal player, out on loan at a succession of clubs. Frosinone of Serie A is the latest to be linked with him while Jenkinson is reportedly a target for Nottingham Forest and West Bromwich Albion.
