40 years ago a group of eleven young men stood in the Estadio Nacional in Lisbon and faced a crowd of 77,000 and the mighty Inter Milan.
They were the first British team ever to reach the final of the European Cup.
Indeed it was the first time their club had even played in the European Cup. And yet they faced one of the richest teams, with a fearsome reputation and an unbeaten defensive strategy.
But these men would go on to make football history... Told by a life-long fan, The Lisbon Lions follows the fortunes of eleven men born within 20 miles of Glasgow who had come to play for a football team struggling in the League.
Reinventing the team with his positive playing strategies, manager Jock Stein guided Celtic to victory in the Scottish championships and eventually to the European Cup itself. Andy Dougan takes us on the thrilling journey with Celtic as, round by round, the team's passion, inventiveness, and above all style brings them to the biggest game in their club's history.
The story remains as romantic, inspiring and stirring as ever.
