In midfield, Paul Nsio, who has marked his league and European debut over the last ten days, joins 16-year-old Aiden McCallion.
Callum Burnside will operate between the lines, flanked by Findlay Curtis and Alfie Hutchison, while Chris Eadie will lead the attack.
Among the substitutes for the Light Blues at The city Stadium are Rydnn McGuire, Oliver Hynd, Oliver Goodbrand, Arran Kerr, Lyle Wark, Cameron Fernie, Lewis Stewart, Alex Smith and Cormac Christie.
