5) Claudio Ranieri
Poor Claudio. Nobody deserved what happened to the veteran Italian boss. Here was a manager who had never won a top-flight league title in his career. He had recently been sacked (rather harshly) by Greece.
And then he only went on to lift the Premier League title in his first season back in England when Leicester City's odds of winning it were an enormous 5000/1.
In a season where all top clubs failed to wrest the initiative, Ranieri's Foxes went on an amazing run and made history. Nobody expected them to defend the title the next season as other clubs reinforced their sides but nobody predicted his fall from grace midway through the season either.
Leicester's poor form was reflective of the way the players were performing on the pitch. Stars such as Riyad Mahrez suddenly looked disinterested and did not bother listening to Ranieri's instructions. The team's slump saw them close to the relegation zone after which the owners took the painful decision of letting him go.
The 65-year-old often left his assistant manager Craig Shakespeare to handle training sessions and it was he who eventually took over when Ranieri was sacked.
The Foxes' change in form was almost instant and they almost managed o finish in the top half of the table, eventually finishing 12th and avoiding relegation.
