Book excerpt: 'I am proud to say that I knew Jock Stein as a football manager, as a colleague and as a friend . . . he was the greatest manager in British football . . . men like Jock will live forever in the memory' - Sir Alex Ferguson During his long reign at Celtic, Jock Stein was a legendary figure in the world of football. He led a youthful Celtic side to a memorable European Cup triumph in Lisbon in 1967 and was in charge of the home-grown Celtic teams which won nine Scottish league championships in a row as well as numerous domestic trophies. Tom Campbell and David Potter have produced an affectionate and in-depth portrait of Stein but are not afraid to delve below the surface of the legend to examine the manager's mistakes and failings as well as his triumphs and strengths. Calling upon such expert witnesses as Bobby Murdoch, Ronnie Simpson and Charlie Gallagher, and on a host of other important figures in the game, this book presents a detailed and fully rounded picture of a man who, at the height of his powers at Celtic Park, revolutionised the game of football in Scotland.
