The Reds and the Owls have endured long seasons in pursuit of a return to the second tier, but the dream will only become a reality for one of the sides. Michael Duff and Darren Moore have the unenviable task of selecting a starting XI for the game, which kicks off at 3pm today (May 29).
The Yorkshire Post has attempted to predict the XI Duff will pick for the Wembley showdown.
