Ghanaian midfielder Joseph Attammah was impressive in his club side victory over Genclerbirgli in the Turkey.
The former Tema Youth player played the full throttle of the game as Basaksehir won 2-1 on Saturday.
Attamah has been deployed as a centre back all season and his timely tackles proved vital as they held on to clinch all three points.
Goals from Mario Massoro and Pektemek was enough to tame the resistant visitors.
Basaksehir are now Europe bound but will be heckling Besiktas at the summit of the log for the ultimate glory in the Turkish Super Lig.
