Second-half goals from Erling Haaland and Phil Foden helped Manchester City to a 3-1 victory over Chelsea, as they replaced the Blues in the Premier League's top four.
Noni Madueke punished a glaring error from City debutant Abdukodir Khusanov early on as Chelsea looked to move five points clear of a rival for Champions League qualification.
Khusanov's attempted header back to Ederson in the third minute was intercepted by Nicolas Jackson, who squared for Madueke to tap home.
However, City began to exert control in an action-packed first half, with Foden striking the post and Josko Gvardiol missing two big chances, while new boy Omar Marmoush saw a close-range finish chalked off for offside.
However, it was third time lucky for Gvardiol as he pounced to tap home when Robert Sanchez could only parry Matheus Nunes' shot, kickstarting City's comeback.
After 68 minutes, Haaland latched onto Ederson's long punt forward and lobbed Sanchez to put City ahead, then Foden raced clear to make the points safe two minutes from time.
The victory takes City up to fourth in the table on 41 points, ahead of fifth-placed Newcastle United on goal difference and one clear of Chelsea and Bournemouth.
Data Debrief: Khusanov's rough start not costly
Thrown in at the deep end with Ruben Dias and Nathan Ake out injured, Khusanov endured a difficult start to his Premier League career.
His weak header led directly to Chelsea's opener, then he earned a fourth-minute booking for chopping down Cole Palmer, the earliest yellow card for a Premier League debutant since Cardiff City's Lee Peltier versus Bournemouth in 2018 (third minute).
However, fellow defender Gvardiol bailed him out with his fifth Premier League goal of the season – more than any other defender has managed in the competition this term and the most by a City defender in a single season since Steve Howey in 2000-01 (six).
A mistake at the other end then helped City complete the turnaround as Sanchez was caught out by Haaland.
No player in the division has made more errors leading to a goal than Sanchez (five) this term.
