This moment was always going to come. From the moment that Duncan Ferguson was overlooked to be Everton's permanent manager, having interviewed for the job in January, there was only one possible path for him to follow.
Ferguson has been assistant to many men in the last decade, from Roberto Martinez to Rafa Benitez, but it was evident to him from the earliest days of Frank Lampard's reign that there would be no space for him in this current set up, no meaningful way for him to contribute.
Football, in the main, has been Ferguson's life and he knows how it works.
