34' - GOAL! #Swans 0-3 Chelsea Football Club (Diego Costa)
It's a three-goal lead now for Chelsea as Fernandez's backpass is capitalised upon by Diego Costa and the striker slots past Fabianski for his second of the afternoon.
36' GOAL! #Swans 0-4 Chelsea Football Club (Oscar)
Now it's Oscar who gets his second of the game as the home side gift possession once more and Costa breaks away to set up Oscar, who slams home into the roof of the net.
It's been a first half to forget for Garry Monk's men, who have been swept aside by the league leaders. Diego Costa and Oscar have both bagged themselves a brace, while it could have been an even greater scoreline after Willian struck the crossbar.
