Thomas Tuchel's Chelsea reign lasted just 19 months. In that period there was a Champions League triumph, a Club World Cup win, a UEFA Super Cup victory, two FA Cup finals and a Carabao Cup final - but not even that was enough to stop his spell at Stamford Bridge being cut short.
When appointed last January, Tuchel became Chelsea's ninth permanent manager since 2010 - with Jose Mourinho's two-and-a-half year stint the longest of any Blues boss in that period. In sacking Tuchel, Todd Boehly has shown a similar ruthless streak what Roman Abramovich consistently demonstrated during his time at Chelsea.
