David Speedie was shown the door by Alan Clarke because of a disciplinary issue and nothing to do with his Ability. Rumour had it that not only was he a big-headed so and so he was very antagonistic with staff and others. Of course I don't know if this was true or ot, but I remember Clarke being a strict manager.Speedie had established himself in the first team. Therefore, it's not that his potential wasn't recognised it was other circumstances, so a poor comparison to Digby situation.
