FC Unirea Constanta

Unirea Constanța was established in the summer of 2021 on the ashes of the former Farul Constanța entity, its berth in the league championship remaining unused after the merger between Farul and Viitorul Constanța. Unirea Constanța unveiled itself as "the team of the South Coast", with local businessman Altay Nuredin being the man who ensures the financing.

Unirea built its squad around former Farul players that did not enter the Liga I project, and started to play its matches in Techirghiol. It seems that the club's plan for the 2022 summer is to rename itself Marina Mangalia and subsequently move to Mangalia for its home matches, in order to be considered a successor club of Callatis Mangalia.

Association with FCSB (2021–2023)

During the first season of activity, after a series of disappointing results, the club was taken over by Vasile Geambazi, FCSB owner's nephew, and Unirea became the satellite of the Liga I team.

Mathematically relegated at the end of the season, but kept in the second tier of Romanian football due to the financial problems faced by Gaz Metan Medias and Academica Clinceni, Unirea Constanța moved to Clinceni, Ilfov County and started the rebranding process to become FCSB A Clinceni.

In the 2022–23 season, Unirea is coached by Dacian Nastai and the team's squad is almost exclusively made up of players on loan from FCSB II.

The fall of Unirea

After FCSB decided not to continue the Unirea Constanța project, the team's owner, Vasile Geambazi, announced that he wants to finish this season and that he is searching for young talents who wants to play for the rest of the season.
