Chelsea were blown away in a 5-0 defeat to title chasers Arsenal in a major blow to their hopes of European qualification.
Leandro Trossard struck a shot through Djordje Petrovic to open the scoring early on and Ben White added a scruffy second just after half-time.
Kai Havertz sealed victory with two second-half goals, soaking in the adulation against his former club. White’s cross found the net minutes later.
It leaves the Blues 30 points behind table-toppers Arsenal and ninth in the table after a truly miserable night.
Nizaar Kinsella was at Stamford Bridge to witness the demolition job.
Djordje Petrovic - 5
The Serb saw a low strike go through his legs after just four minutes but was very busy and made several sensational saves despite the scoreline.
Alfie Gilchrist - 4
The 20-year-old faced a baptism of fire on his Premier League debut and was at fault for the first goal.
Axel Disasi - 4
The defender was caught on his heels from a flick-on and missed a chance to equalise midway through the first half.
Benoit Badiashile - 4
Badiashile produced the flick-on to create Disasi’s chance but wasn’t solid defensively and was at fault for Havertz's second
Marc Cucurella - 4
Bukayo Saka had the beating of Cucurella, who seemed distracted by arguing with officials. Poor for Havertz and White's second goals.
Moises Caicedo - 5
The best of the three midfielders and made one crucial interception to stop a tap-in, but was still overrun by a world-class Declan Rice in particular.
Enzo Fernandez - 4
He scuffed a chance wide, got booked and played White on for his goal.
Conor Gallagher - 4
The midfielder produced a good cross early on but got caught in possession a lot as Chelsea lost the midfield battle.
Noni Madueke - 4
Dangerous on the transition and created the best chance of the game but left Gilchrist badly exposed defensively.
Nicolas Jackson - 5
Impressive until he reached the penalty area. Finishing once again let him down.
Mykhailo Mudryk - 4
Predictably poor tactically and needed to be coached through the game by Pochettino.
Substitutes
Trevoh Chalobah - 5
He could not do much after coming on and the goals kept flowing.
Raheem Sterling - 5
The 29-year-old will have been angry not to start but produced just a tame free-kick.
Cesare Casadei - 5
The Italian at least didn’t see Chelsea concede while on the pitch.
Thiago Silva - 6
The 39-year-old came on to try to stop the rout as Chelsea’s turned into a back five.
Unused subs Silva, Bettinelli, Chukwuemeka, Washington, Tauriainen, Dyer
