Book excerpt: Charlie Miller was the best young Scottish footballer of his generation. He made his Rangers debut under Walter Smith aged just seventeen and became a vital part of the lbrox club's legendary nine-in-a-row squad. Miller won four league titles, two Scottish Cups and one League Cup with Rangers, as well as being named the Scottish PFA Young Player of the Year in 1995. Yet many believe he was a wasted talent. Here, Miller reveals how he's spent his entire life not knowing who his father is and relives his colourful upbringing in Castlemilk - one of Glasgow's toughest housing estates. He explains how the gang culture he was involved in almost ended his Rangers career before it had started and speaks openly about the impact drugs, alcohol and gambling has had on his life. Miller takes you inside the lbrox dressing-room, where he mixed with iconic figures like Ally McCoist, Brian Laudrup and Paul Gascoigne and explains how he went from Rangers hero to rock bottom.
