Club career
Early career
Delianov started his career at Melbourne City where he was named as one of the best young goalkeeping prospects in the country.[5][6] He was added to the first team squad after signing on a two-year scholarship contract in March 2017.[7]
Delianov made his debut on 26 April 2019, after spending two years as a third-choice keeper, in a 5–0 win against Central Coast Mariners at Melbourne Rectangular Stadium.[8] Despite keeping a clean sheet in his maiden appearance, Delianov was released by Melbourne City a month later.[9]
Delianov signed a two-year deal with Adelaide United on 11 November 2020, following his departure from Melbourne.[16] He made his debut on 28 December 2020 in a goalless draw against his former side Western United, keeping a clean sheet at GMHBA Stadium.[17][18] Delianov was voted RAA Travel Members' Player of the Month twice consecutively by March 2021, having made 41 saves and keeping three clean sheets in total.[19] He was later ruled out with a hamstring injury during that month and temporarily replaced by Joe Gauci.[20]
He played in Adelaide's last match on 19 June 2021, saving a penalty during a 2–1 semi-final defeat to Sydney FC.[21] Delianov remained as a first-choice keeper in his second season, playing in the opening seven league matches before suffering a shoulder injury.[22] He was replaced by Joe Gauci in goals for a second time, although after his return, Delianov remained on the bench in the following matches.[23] He extended his contract with Adelaide United on a renewed two-year contract in June 2022.[24]
After Gauci was absent due to international football,[25] Delianov made his first appearance for United, following two years on the bench (his last being on New Year's Day in 2022), on 4 January 2024 against Wellington Phoenix.[26]
