Approximately 52 managers have either been sacked or resigned from their managerial posts in the four divisions of English football in the 2012-13 season.
Coventry City were the first club to blink first, sacking Andy Thorn on 24 August, while the most recent manager to depart was Kenny Jackett, whose resignation was "reluctantly" accepted by Millwall on the same day Dean Saunders was dismissed by relegated Wolves
Michael Appleton left two jobs and was sacked from another, as Blackburn went through the most changes.
