There might be two divisions between City and FC Halifax Town, plus the fact that Sunday's match is the first competitive meeting between the clubs in over 16 years, but there are still plenty of reasons to link the Bantams with their F.A Cup first round opponents.
Out of FC Halifax's current playing squad, four of them have represented City earlier in their careers.
Goalkeeper Matt Glennon, who is likely to start on Sunday, played for the Bantams for a four-month period back in 2010.
Defenders Steve Williams and Simon Ainge, both also expected starters come Sunday, have worn the colours of the Bantams in the past as well.
Signed by Stuart McCall in July 2009, Williams made 68 appearances for City before eventually leaving the club four years later at the end of 2012/2013 season. Ainge left Valley Parade in 2009 having featured 16 times for City following his emergence from the club's youth set-up.
The fourth former Bantam in the FC Halifax playing ranks is midfielder Jon Worthington, who played for City under Peter Jackson during the 2010/2011 campaign.
While still being registered as a player for FC Halifax, Worthington now also operates as the Shaymen's physio.
FC Halifax chairman David Bosomworth is a Bradford City fan and has worked with the club in the past, most importantly, helping the Bantams through the tricky period of administration back in 2004.
On the Bradford side of the coin, City goalkeeping coach Lee Butler enjoyed three separate spells with Halifax during his playing days, making over 130 starts for them in the process. Butler also had a period working for Halifax as a coach.
Legendary former City defender and assistant manager Wayne Jacobs was also assistant to another ex-City player, Chris Wilder, for two years at Halifax.
Jacobs and Wilder both finished their playing days at Halifax as well.
Popular striker Bobby Ham, who made over 190 appearances for the Bantams over two separate spells, is now a director at FC Halifax.
Lee Elam - a leading member of City's youth coaching set-up - played for Halifax back in 2003.
And that's not all. Some of the other notable names to have featured for both Halifax and Bradford in the past include:
City's previous visit to The Shay Stadium for a competitive fixture came back in September 1998 for the first leg of a League Cup tie, which the Bantams won 2-1. City also won the return leg 3-1 at Valley Parade to defeat Halifax 5-2 on aggregate.
City would go onto face Leeds United in the next round before eventually securing promotion to the Premiership at the end of that season.
