Serdar Aziz (born 23 October 1990) is a Turkish professional footballer who plays as a centre back for Turkish club Fenerbahçe in the Süper Lig.
Aziz was born in Osmangazi, Bursa. His father was born in Bitola, North Macedonia from a distant Kosovo Albanian family origin and his mother was born in Bursa. He has two older siblings, one brother and one sister. Aziz's father was an amateur footballer in Bursa. At the age of 10, Aziz enrolled in a football school in Bursa. He spent 2 months at the school before he was signed to a youth contract by Bursaspor. Aziz originally played in midfield due to his small stature. However, Aziz pleaded his coach to place him as a center back because he believed he wasn't good enough technically to play in midfield. Aziz had a growth spurt soon after, which cemented his position at stopper.
Raşit Çetiner called Aziz up to the senior squad in 2006. Although he did not make his debut, Aziz was allowed to train alongside the senior players. He was loaned to feeder club Bursa Merinosspor for the 2007–08 season. Aziz was not open to the move, but warmed up to the idea after he realized the club was virtually one and the same with Bursaspor. He admitted the physical nature of the TFF Third League helped aid his development into becoming a professional center back. Aziz made his professional debut for Bursaspor on 25 October 2008 against Fenerbahçe, with Bursaspor losing 2–5. He was a part of the Bursaspor squad that won the Süper Lig in 2009–10.
