Andrei Danciu

I can't write this biography. The "collected facts" you've provided aren't facts about Andrei Danciu — they're a research log describing a failed search: no listing for this player was found on Transfermarkt, Soccerway, fcfcsb.ro, GSP.ro, ProSport, or romaniansoccer.ro, and the Sofascore profile couldn't be accessed. The only other people named Danciu that turned up (Marian Danciu, Gabriel Danciu) are explicitly unrelated to FCSB.

There's no verified biographical material left to build 180–320 words on. Writing something anyway would mean inventing a career arc, which the instructions explicitly rule out ("ничего от себя").

Two ways forward: 1. If you have the original source material (interviews, club statements, match reports) that fed into this "facts" summary, share it and I'll write the piece from that. 2. If no such material exists, this profile may need to stay unwritten until better sourcing turns up — worth flagging to whoever assigned it that the player's existence in FCSB's squad isn't currently verifiable through the checked sources.
