Leeds United pulled off a huge 3-1 win over Chelsea at Elland Road to move three points clear of the Premier League relegation zone and ease the pressure on head coach Daniel Farke.
In a game that could have been pivotal for Farke's future, his decision to stick with the 3-5-2 formation that inspired a second-half fightback in the defeat at Manchester City proved to be decisive as they brushed Chelsea aside to end a four-game losing run.
Impressive performances over Arsenal and Barcelona had elevated Chelsea into the title conversation, however the trip to West Yorkshire delivered a reality check for Enzo Maresca, whose side slip down to fourth, nine points adrift of the league-leading Gunners.
Leeds deservedly led by two goals at the break after a bullet header at the near post from Jaka Bijol and a stunning long-range strike from Ao Tanaka at either end of a half that Farke's side had dominated with Chelsea registering just a single shot on target.
Maresca's double half-time change brought about an instant impact as Pedro Neto pulled a goal back off the bench soon after the restart, taking advantage of a slip in concentration from Leeds defender Gabriel Gudmundsson to poke in at the back post.
However, Leeds refused to back down and restored their two-goal advantage as Dominic Calvert-Lewin scored for the second game running after substitute Noah Okafor capitalised on a loose pass from Chelsea defender Tosin in his own box.

Neville: Chelsea a short of being title contenders
Sky Sports' Gary Neville:
"Chelsea will be in the top four or five, no problem.
"But when you talk about Chelsea winning the league, they are short in goal, short at centre back and short up top.
"Their centre forwards, centre backs and goalkeepers aren't good enough to be title winners."
