Antonio Conte cut a drawn figure on the touchline and it looks as though he may have led his Blues out in a Premier League game for the last time. That is unless Chelsea owner Roman Abramovich has made a complete U-turn in his approach to running the football club... yeah, we can't see it either.
It's not been a good week at Stamford Bridge but it's far from Chelsea's first stumble under the watchful eye of the Russian billionaire. Here are six of the worst Chelsea defeats since 2015.
6. Manchester City 3-0 Chelsea (August 2015)
Chelsea were expected to lay down a marker early in their 2015 defence of the Premier League title but came up horrendously short against Manuel Pellegrini's title hopefuls Manchester City, putting in a woeful performance.
Their second game of the season became one to forget for Blues fans as goals from Sergio Aguero, Vincent Kompany and Fernandinho sealed victory for the Citizens on the day.
Further drama unravelled as the home fans goaded Mourinho for sidelining team doctor Eva Carneiro, after she ran on the pitch to treat Eden Hazard during Chelsea's 2-2 draw at home to Swansea on the opening day.
5. Everton 3-1 Chelsea (September 2015)
Chelsea suffered a third defeat in the opening five games of their Premier League defence - their worst top flight start since 1986 - under Mourinho in September of 2015.
Steven Naismith netted a hat-trick at Goodison Park on what was a seriously embarrassing day for the travelling fans and Mourinho.
Nemanja Matic gave his side brief hope in the game after clawing the score back to 2-1, but Naismith's third goal eight minutes from time sealed the visitors' fate and victory for Everton.
4. Chelsea 1-3 Southampton (October 2015)
Next in the list is Chelsea's poor home defeat to Southampton in 2015. Stamford Bridge was initially optimistic after Willian struck a fantastic free-kick in the 10th minute, giving his side the lead.
However, things descended and goals from Steven Davis, Sadio Mane and Graziano Pelle earned the Saints a deserved win as Chelsea slumped to 16th in the Premier League table.
Mourinho's problems were compounded as he received a fine and a one-game stadium ban after accusing referee Robert Madley of being 'afraid' to give his side decisions.
3. Chelsea 0-3 Bournemouth (January 2018)
Antonio Conte's side were easily dispatched by Eddie Howe's travelling Bournemouth in January, in a game that matched the joint-heaviest defeat of the Italian's two-and-a-half-year tenure.
The Cherries hadn't registered a win since their 1-0 victory at Newcastle in November but dominated at Stamford Bridge, with Callum Wilson, Junior Stanislas and ex-Blue Nathan Ake netting against an insipid Chelsea.
Conte was dismayed at his outfit's defensive display, with the side having kept five clean sheets in the last seven prior to the game.
2. Watford 4-1 Chelsea (February 2018)
A week after the home rout to Bournemouth, you would think Chelsea would be a bit more savvy and focused when travelling to Vicarage Road, right?
Chelsea's squad is currently down to the bare bones and the team looks worryingly leggy. Playing with 10 men for an hour did not help, as underwhelming summer signing Tiemoue Bakayoko received a second yellow in the space of 10 minutes and was dismissed.
A brief moment of brilliance from Eden Hazard was all Blues fans could enjoy, with the Belgian equalling the score from range. But all that did was spur the home side on and once again Chelsea capitulated defensively as the Hornets netted three in seven minutes.
1. Chelsea 2-4 Bradford City (January 2015)
Jose Mourinho declared it would be a 'disgrace' if his rotated Chelsea side were to be knocked out of the FA Cup by lowly Bradford City...awkward.
Chelsea looked on course for a routine victory after going two ahead inside 38 minutes, but Jon Stead fired back just before half-time to keep their cup dream alive. The goal proved to be the catalyst for an immense performance after the interval as Filipe Morais, Andy Halliday and Mark Yeates netted in a rampant second half from the League One side.
This result is arguably Chelsea's worst in recent history, and certainly takes the crown for most embarrassing defeat under Abramovich's reign.
