#4. Rendy Lerner (Aston Villa)
Having sold its best players in the form of Christian Benteke, James Milner and Fabian Delph, Aston Villa had no clue of what were they doing under the administration of Rendy Lerner. While he fell out with fan favorite Martin O’Neill on the issue of new transfers, the former Villa Manager then resigned from his post six days before the start of the new season. So a club which finished 6th in 3 successive seasons under Martin O’Neill then went on to flirt with relegation for the next few seasons before finishing rock bottom at the end of 2016/17 campaign.
