Viitorul Constanța Nedelcu made his professional debut for
Viitorul Constanța on 18 July 2014, in a 3–3 draw with
Botoșani counting for the
season's
Cupa Ligii; Viitorul went further after a 5–3
penalty shoot-out win. His first appearance in the
Liga I came ten days later, in a goalless draw at
CSM Studențesc Iași.
FCSB On 10 August 2017, Nedelcu signed a five-year contract with
FCSB, one month after having initially refused to do so by arguing that he dreams of playing abroad. Him and his Viitorul teammate
Romario Benzar were acquired by the
Bucharest-based club for a combined cost of
€2.7 million, and an additional €500,000 fee was paid for Nedelcu in November to remove an interest clause in his deal. Nedelcu made his debut for the
Roș-albaștrii in a 1–1 league draw with
Astra Giurgiu on 12 August 2017. On 5 November that year, he scored his first goal in a 2–1 victory over
Concordia Chiajna.
Loans to Fortuna Düsseldorf and Farul Constanța Nedelcu often struggled with injuries during his stint in the capital, and on 12 June 2021 was sent out on a one-
year loan with a purchase option to
2. Bundesliga club
Fortuna Düsseldorf. On 4 February 2022, after his loan at Fortuna was cancelled prematurely, he moved to his boyhood club Viitorul—now renamed
Farul Constanța—on loan for the remainder of the
campaign.
Farul Constanța On 14 June 2022, Nedelcu moved to Farul Constanța on a permanent basis after signing a three-year contract. ==International career==
