Tangled Up in Blue explores the stories behind two of Scottish football’s defining issues, which are separate but closely linked. First, the historic and fractious rivalry, based on a religious divide, between Glasgow Rangers and Celtic; and, second, the recent catastrophic financial collapse of Rangers, which ultimately led to the club’s liquidation.
