The fourth-placed Bantams head into Sunday’s televised date at Glanford Park with a two-point advantage on their hosts, who sat ten points ahead of McCall’s men when the sides played out a goalless draw on Boxing Day.
Having led League One at the start of last month, Scunthorpe have crashed to fifth after losing five of the last six games whilst Bradford have gained 11 points on them in the same period.
“After the last game against Scunthorpe, you probably wouldn’t envisage with the gap we had that we would manage to be above them before we played them again,” McCall told the Telegraph and Argus.
“But that shows everyone what can happen.
“It’s not where you are on December 26, January 1 or after Sunday’s game. It’s about the final table when we come off the pitch on April 30.
“I keep saying it but it’s true. That is the only time it matters.”
Sunday’s game against the Bantams kicks off at 12.30 and is live on Sky Sports 1.
