Greek side AEK Athens have also been closely linked with the 28-year-old centre-back.

Galatasaray have had a quiet transfer window compared to their cross-city rivals Fenerbahçe who have already made eight transfers this summer.

The Istanbul giants have however, completed the signings of Arsenal forward Lukas Podolski, Turkish international Bilal Kısa and Jem Karacan.

The reigning Turkish champions lifted the Süper Lig title for a record 20th time last season and then went onto win the double after beating Bursaspor 3-2 in the Turkish Cup final – 16th Turkish Cup title.

The Lions have now won the double a record six times and booked a place in the Champions League group stages for the fourth consecutive season.
