On 1 July 2026 the KAP screen filled up. Trabzonspor bundled the domestic and youth line into one filing: centre-back Samet Akaydın, defensive midfielder Melih Kabasakal, winger Metehan Mimaroğlu, 18-year-old Thierry Darnel Karadeniz.

Samet Akaydın

Free from Rizespor. 2+1 years, option with the club. Guarantee: 43.5 million TL in 2026/27, 53.875 million TL in 2027/28. Option 2028/29: 60.1 million TL. Agency: 4.6 percent of the gross wage.

Melih Kabasakal

From Gaziantep FK. Release fee 22.5 million TL VAT included, three instalments. Contract 2+1. 2026/27: 30.575 million TL guaranteed; 2027/28: 37.628 million TL. Option 2028/29: 43.6725 million TL.

Metehan Mimaroğlu and Thierry Karadeniz

Mimaroğlu from Gençlerbirliği, Karadeniz from Köln U19, both free. Both on the same KAP day. Karadeniz is 18; after the signing Transfermarkt lists him on loan at Sebat SK — first-team minutes are another matter.

This four is not a star move; it is squad depth. The big names are Salah, Aral, Franculino Djú at Trabzonspor. Full list: 2026/2027 transfers.
