The Turkish transfer window shut on Monday 2 September after a record-breaking summer for Super Lig clubs.
The league made a record earning from transfer sales.
In total, 345 players were sold in total for a combined fee of £73.9m – the highest figure on record.
The most expensive transfer sold was Yusuf Yazici’s move from Trabzonspor to Lille for £14.85m, followed by Napoli signing Eljif Elmas from Fenerbahce for £14.4m and Sassuolo landing Merih Demiral for an £8.33m fee from Alanyaspor – who was sold to Juventus for £16.2m the same transfer window.

They mark the growing trend of young Turkish players sold to top five leagues – Premier League, Serie, A, Bundesliga, La Liga, Ligue 1 – from the Super Lig.
Twenty-two-year old Mert Cetin moved directly from Genclerbirligi in the Turkish second-tier to Roma for £2.7m.
Last January 19-year-old Ozan Kabak was snapped up by Stuttgart before being sold to Schalke this summer and Demiral moved to Sassuolo on loan.
The previous summer Lille signed Mehmet Zeki Celik from Turkish second-tier side Istanbulspor and Trabzonspor sold Okay Yokuslu to Celta Vigo.
