One of the four giants of Turkish football, Galatasaray Football Club, has decided to unilaterally terminate its kit sponsorship deal with Dumankaya Construction. According to team officials, during Tuesday's board meeting, the ongoing kit sponsorship deal with Dumankaya Construction was unilaterally terminated.As part of the ongoing investigation by Istanbul's Anatolian Side Public Prosecutor's Office into allegations of providing financial support to the alleged Gülenist Terror Organization (FETÖ)/Parallel State Structure, Dumankaya İnşaat's owners have been listed among the suspects. It has been suggested that managers told Galatasaray Football Club President Dursun Özbek that the club should part ways with the kit sponsor firm, and Özbek later started the process of removing the sponsor.While Galatasaray are in only the sixth month of the two-plus-one-year contract with Dumankaya İnşaat, work to terminate the contract as soon as possible has begun. The club is planning to complete the procedure before the Bursaspor match. Galatasaray can go out onto the field without any bearing sponsor's names on their jerseys, according to recent reports.
