"The chairman represents Wigan," Martinez said. "He had this dream and we are going along with him.
"For him to be leading the team out will be a fitting moment for his career."
Amazingly, Martinez finds himself facing a familiar figure in the opposite dugout in Kenny Jackett, who made him captain at Swansea, where they spent two years together.
"Kenny has had real success over the last few years but that is no surprise to me," Martinez said.
"It will be great to see him again but this game is not about managers. It is about two sets of players who will both be giving it everything to reach the final."
