The Bantams have completed deals to bring young professionals Lachlan Barr and Joel Grodowski into the football club.
Barr, 22, and Grodowski, 19, have both penned deals at the Northern Commercials Stadium, with the former signing a deal until January and the latter signing a one-year contract.
Barr is an Australian-born centre half formerly of Adelaide United. The defender spent a period training with the Bantams last season. The club he was most recently with was FC Internationale Berlin.
Promising forward Grodowski scored 94 goals in two seasons for PSV Bork in the German regional league, including 53 in 30 games last term, and almost secured a move to Borussia Dortmund II (Second team).
The pair are expected to make up part of the Club's development squad.
