Ruben Zadkovich

Born in Fairfield, Sydney, New South Wales, Zadkovich had previously played for English Football League club Notts County, scoring on his debut against Chester City, as well as Queens Park Rangers and Australian side Wollongong Wolves. He has also made several appearances for the Young Socceroos, most notably at the FIFA World Youth Championship.

Sydney FC

Following his time in England, Zadkovich returned to Australia in late 2005 and trialled for Sydney FC. He travelled with the squad to the FIFA Club World Championship and despite not making an appearance he impressed coach Littbarski, being called in as a short-term replacement for injured Ufuk Talay late in the season. After a 12th-minute debut off the bench against Queensland Roar, Zadkovich scored on his first start, against Perth Glory, during Sydney's run to the inaugural A-League championship, earning him a two-year full-time contract. He was allowed to leave the club in March 2008.

Derby County

On 17 April 2008, it was revealed Zadkovich had signed a two-year deal with English club Derby County, although his registration was unable to be completed before 1 July. Zadkovich made his Derby debut as a second-half substitute against Norwich City at Pride Park in October 2008, in a match which Derby won 3–1. He struggled with injuries during his time at Derby and, after seven appearances for the club, cancelled his contract by mutual consent on 23 January 2010.

Perth Glory

Zadkovich was appointed assistant manager of Perth Glory in October 2020. In March 2022, he was named interim head coach of the Glory following the departure of Richard Garcia. The 2021–22 season ended with Glory finishing bottom of the A-league table for the first time in their history. He was appointed as permanent head coach in May 2022. During the 2022–23 season, news surfaced that Zadkovich had punched midfielder Giordano Colli during training, with the coach moving quickly to dispel any notion of a rift.
