In the days before Christmas 1963, West Bromwich Albion's first-team players revolted. It was bitterly cold, but their manager would not let them train in their full tracksuits.
Temperatures were hovering around zero, the ground was rock hard, and other top teams had escaped to practise on the continent.
But at the Baggies' training ground in Smethwick, manager Jimmy Hagan instructed his men to show up in their usual gear of shorts, T-shirts and a sweatshirt.
Graham Williams, who played for the team for almost two decades, remembered player-manager relationships were already strained: "He was so strict, and it wasn't fun to be there," he said.
