Chelsea's stunning first-half salvo put Swansea to the sword and kept the pressure on Manchester City to deliver at the top of the table.
Two goals apiece for Oscar and Diego Costa inside 36 minutes gave Jose Mourinho's men a commanding half-time lead, before Andre Schürrle added a fifth to ensure a thoroughly miserable afternoon for Garry Monk's men.
