The Latics take on Millwall in the FA Cup semi-final, 53 years after what should have been the most memorable day of Whelan's life ended in abject misery.
As a defender with Blackburn, Whelan knew victory over Wolves could not be guaranteed in the FA Cup final - but not in his worst nightmares could he have anticipated being carried off on a stretcher with a broken leg.
It left mental scars that never seem to have quite healed.
But Martinez feels that will eventually happen this weekend.
"It will be a significant day for the chairman because he has been through such a lot," the Spaniard said. "The FA Cup is something very special for him.
"Not many people had the experience he did in the 1960s, with the final and being carried off.
"There is a sense of unfinished business. It is a unique way of closing that circle."
