Derek Dougan was no ordinary footballer. A flamboyant Northern Irish goalscorer, his unwillingness to accept injustice and mismanagement won him as many enemies as friends. Shortly after being asked to collaborate on a new autobiography, a project undone by Dougan's sudden death, David Tossell set out to retrace his life through a series of over 70 interviews. The result is a definitive account of a contradictory icon with a unique place in the evolution of modern British football. Dougan demanded a transfer on the eve of an FA Cup final, quoted Voltaire and fell out with various clubs. As chairman of the PFA, he fought for freedom of contract; as a club executive, he introduced shirt sponsorship; and 'The Doog' saved Wolves from extinction. In Sunshine Or In Shadow reveals the darkness and light of Derek Dougan, the drive and demons that kept him fighting to the very end.
