Old Firm in shambles: Inside Celtic & Rangers' rough seasons
Scottish football has been dominated by two clubs since forever. The country's first season of top-flight action in 1890-91 saw Rangers share the crown with Dumbarton as joint-winners, while Celtic finished third in the 11-team division. Since its inception, the title has only gone to a team outside the Old Firm 19 times, with the Glasgow duo taking home the remaining 110.
