 By this point, Celtic were experiencing one of the most difficult spells in their history, and 1990–91 brought further disappointment, with no trophies and a League Cup Final defeat to Rangers.In 1991–92, new manager Liam Brady continued to select Miller but results deteriorated further, with defeats to Airdrie in the League Cup, Neuchâtel Xamax in the UEFA Cup and Rangers in the Scottish Cup (despite David Robertson having been sent off in the opening minutes for a challenge on Miller, breaking two of his ribs).By 1992–93, another campaign which would bring not even as much as a final for Celtic, Miller was often only being selected as a substitute with Brady's own signing Stuart Slater being preferred.
