The Millers, without a win in five matches, put their Yorkshire rivals to the sword early on last season, winning 4-0 on the Bantams' first visit to their new home, and then won the reverse fixture in April to all-but seal promotion.
There is no love lost between the two sides, who have been in the same league for 12 of the last 13 seasons, and Bradley wants another victory, not only to give the supporters bragging rights, but also to kick-start their stuttering league form.
"It is obviously a big competition in England and with it being a local derby hopefully we can put on a good show, get a win and get into the next round which will give us confidence for the league," he told Press Association Sport.
"We love that it's a local derby and a big game with hopefully a big crowd.
"We know it's a big game with the reaction to us beating them 4-0 last year, so hopefully it will be a great atmosphere and we can get a similar result."
