Roy Keane helped Sir Alex Ferguson implement an “unspoken rule” in training in order to ensure Manchester United’s players didn’t drop their standards.
United of course dominated English football under the management of Ferguson, with their best years arguably coming with Keane as their captain. With the pair working together, United won seven league titles, four FA Cups and the 1999 Champions League as part of a historic treble.
Keane is of course famous for his no-nonsense approach, which would ultimately lead to his departure from Old Trafford following a falling-out with Ferguson. Before that though, the former Republic of Ireland international worked as Ferguson’s right-hand man on the training ground.
