Servet Çetin

Early career

Çetin joined Kartalspor in 1990 after the club manager called his house looking for his older brother İrfan who was playing as a midfielder for the club at the time. Servet informed the club's manager that his older brother was not home and would not be returning until later that evening. The club's manager, in a bind to find players for the match later that day, questioned Servet's interest in football and upon learning that he was interested, Servet was invited to join the club as an amateur player and played in the match later that day as a right-back. Servet was signed onto professional terms at the start of the 1999–2000 season. He joined Göztepe at the start of the 2001–02 season. Having a successful first season in the Süper Lig his club finished 7th and missed out on a UEFA Cup berth. He was signed by Rıza Çalımbay for Denizlispor at the start of the 2002–03 season in a deal which also involved Ersen Martin and Mustafa Özkan. Despite missing out on the UEFA Cup with Göztepe, Çetin got a chance to play European football at his new club as Denizlispor. He was an integral part of the team which eliminated Lorient, Sparta Prague and Lyon in the first, second and third rounds of the competition respectively. In the fourth round, Denizlispor lost to the eventual winners José Mourinho's Porto. Çetin had become a household name in Turkish football with his performances for Denizlispor in the league as well as for the Turkey Under-21.

Çetin progressed through the youth ranks of the Turkey national team, from Under-17 to the full senior squad. He made his debut for Turkey in a 4–0 friendly match loss against Czech Republic on 30 April 2003, coming on for Alpay Özalan in the 83rd minute. He made two appearances at the FIFA Confederations Cup in 2003. He captained the international side for the first time during Turkey's 2–1 win against Bosnia and Herzegovina in October 2008. Çetin played in the qualifiers for the European Championships and featured in the finals of the tournament itself. However, he picked up injuries during the group stages and meant he could only feature in three of Turkey's games as they progressed to the semi-finals.

From 2017 to 2023, Çetin served as an assistant coach under Rıza Çalımbay's leadership. This period prepared him for his next step. On 26 June 2023, after Rıza Çalımbay left Sivasspor, Çetin took over as the head coach. This transition showcased his evolution from a player to a coach, and his new role presented opportunities to apply his football knowledge and leadership skills.

Çetin is known as 'Bionic Servet' for his strength and bravery to push on playing despite serious injuries. In UEFA Euro 2008 his injuries included a torn groin, strained knee ligaments, a broken tooth and a bruised hip bone all at once. Another nickname used for Çetin is 'Terminator Servet' due to the face-mask he obtained after his cheekbone was broken.
