Chelsea manager, Enzo Maresca, has admitted his team was “poor” in the 3-1 defeat to Leeds on Wednesday night and did not deserve to win.
Jaka Bijol and Ao Tanaka scored twice as the host went into the break two goals up.
Pedro Neto pulled one back for the Blues after the break, before Dominic Calvert-Lewin pounced on a defensive error to seal victory.
The result leaves Chelsea nine points behind table toppers Arsenal.
Maresca, speaking to BBC Match of the Day, said: “A very poor night, they [Leeds] deserved to win the game, they were better in all aspects.
“[We will] Just try to analyse and learn from this game and focus on the next one.
“After the goal we scored we had one or two clear chances, but the third goal killed the game completely, then it’s much more difficult.”
