Is this the end of Jose Mourinho at Chelsea?
The Blues fell over like a pack of cards against an average Southampton - losing 3-1 at Stamford bBridge after going 1-0 up thanks to a sensational strike by Willian. And we're rightly booed off the pitch by their own fans at the end.
For 25 minutes this looked like a Chelsea side restored to greatness. The remaining 20 minutes of the half saw the Blues retreat back into their shells and concede a sucker punch of an equaliser.
Quite what happened to them in the second half is a mystery worthy of an Agatha Christie plot.
The play was shambolic, the side simply stopped playing and the Saints gained confidence that by rights they should not have had.
Some individual errors resulted in goals and now the Blues must be looking downwards to the bottom of the table rather than the Promised Land of the top.
Will Mourinho still be in a job at SW6 when the league programmes resumes in two weeks time - it's international week - that is the question.
The early encounters were pretty even, with misplaced passes and over hit balls from both sides.
A searing run by Eden Hazard on eight minutes resulted in him being upended by ex-Blue Oriol Romeu.
Willian opted to take it. Now bearing in mind the last three times he took a kick from the same left position, he scored .
So he ran up and thumped it with a massive amount of serve added.
The ball sensationally zipped through the air, it seemed to gain height three-quarters of the way and arrowed past Maarten Stekelenburg and crashed into the back of the net to put Chelsea 1-0 up.
But the Saints were not downhearted and attempted to claw their way back into the game quickly. Steven Davis was unlucky that his right-footer on 16 minutes only dented the side-netting.
Chelsea dodged a bullied on 32 minutes when Ramires appeared to hack down Sadio Mane. The Saints player made a theatrical end to his fall, which probably convinced referee Robert Madley that he dived.
The player then went into the ref's book following another easy collapse to the fall.
Five minutes before the break Hazard gave the ball away in midfield. mane fed Ryan Bertrand on the left and the other ex-Blue in the Saints side took a shot from an acute angle on the left. Thankfully for Hazard, Begovic was quick to the danger and smothered the shot for a corner.
Ramires was next in the book for Madley for upending Mane, this time in midfield. From the resultant kick, a minute before the break, the Blues we're caught cold.
The ball was passed to Graziano Pelle who chested the ball to Davis, who was unerring with a daisy-cutter from just outside the Chelsea penalty area and the ball beat Begovic at his near post for an unlikely equaliser.
Jose Mourinho replaced already booked Ramires for Nemanja Matic at half-time while Ronald Koeman took off another already booked player - Romeu for James Ward-Prowse.
After a nervous opening to the second-half, when Chelsea could have gone behind but for a fine save by Begovic from Mane.
Madley was the centre of attention on 58 minutes when he gave a yellow card to Radamel Falcao for diving when the Colombia on-loan striker was put clean through by Fabregas.
But on 60 minutes when Branislv Ivanovic headed a poor ball to Cahill who then promptly lost possession, Chelsea were under instant pressure. John Terry and Cesar Azpiliceuta then both failed to halt Mane's run and he slotted the ball home, under Begovic body to go 2-1 up.
Worse was to follow on 72 minutes when following a quick counter-attack, the Blues defence was blown apart resulting in Pelle to arrow home the third goal from just inside the Chelsea area, with Begovic well beaten.
Sensationally Mourinho then hauled off substitute Matic as he replaced him with striker Loic Remy.
Falcao saw a decent free-kick deflected foe. Corner on 86 minutes but by then the drama age was well and truly down.
This truly dreadful second half could not end quick enough for players and manager and they were rightly booed off at the end.
