Career
Trabzonspor
Karadeniz played his first professional match for Trabzonspor in the 1999-1900 season at the senior level and made ten appearances. He was at first used in defensive roles by his manager, but was gradually given a more and more offensive role in the team until the 2003-2004 season when he was given an attacking midfield role. His lightning step and effective understanding with teammate Fatih Tekke enabled him to lead the club in scoring that season with 13 goals.
Rubin Kazan
On 13 March 2008, he signed a five-year deal with the Russian club Rubin Kazan worth €8.7 million.
Karadeniz mentioned that it was sad for him to leave Turkey and also said he chose the club because he felt that if he had joined a big team in Europe his club would not have gotten as much money for him. On 20 October 2009, Karadeniz scored the winning goal to shock the Barcelona fans at Camp Nou, winning the match for Rubin Kazan.
He played his national team debut against Czechoslovakian Republic national football team on 30 April 2003. He also played 2 times for Turkey B national football team for Future Cup matches against Scotland and Germany and 16 times for Turkey U21.
He was called up for the Union of European Football Associations Euro 2008 for Turkey.
