City have signed teenage striker Mason Bennett on loan from Derby until January.
The pacy 18-year-old, an England under-19 international, can play on the wing or down the middle.
Bennett made Derby history as their youngest-ever player when he made his debut at Middlesbrough in 2011 aged 15. He is also their youngest goalscorer.
He spent a month on loan at Chesterfield last season but is seen as a massive prospect at the Championship club and signed a new four-year deal last month.
Derby head coach Steve McClaren said: “He needs first-team football to continue his development and heading to Bradford on loan is a good move for all parties.
"We will follow Mason’s progress very closely throughout the duration of his time at Bradford but it goes without saying we hope he enjoys a successful time there."
