Swansea 0-5 Chelsea
Rampant Chelsea romped to victory over a sieve-like Swansea, in a performance that was sometimes sublime and always controlling.
The Blues started the flow from the very first minute, as they systematically took apart Garry Monk's side at The Liberty.
The dream start came when Oscar pounced on a mistake by Gylfi Sigurdsson and fired in from distance after just 50 seconds.
For the second on 20 minutes, Cesc Fabregas, Willian and Oscar worked a pretty little triangle before the first of the three passed to Diego Costa, who caught the defence napping to slot home.
The third was Diego Costa's second 14 minutes later, and a howler of an error from Swans Federico Fernandez, who unwittingly passed to the waiting striker in the box for the assist.
And two minutes later it was four – Oscar the beneficiary of a cut back from the right after a Willian long ball.
Amid all of this, Willian managed to hit the woodwork twice in 45 pulsating minutes of relentless football.
The second half was far more pedestrian – it didn't really need to be anything more.
However, Chelsea remained well on top of a Swasnea side that showed only a modicum of additional organisation.
Blues eased up towards the end, Jose Mourinho resting a series of players with the League Cup semi final first leg at Anfield in mind.
But Branislav Ivanovic, roaming up the right, combined with Eden Hazard to prove supplier for a fifth on 79 minutes – turned in by sub Andre Schurrle.
It was Swansea's biggest home league defeat at The Liberty – and Mourinho's biggest away league win with Chelsea.
Blues go five points clear with closest chasers Manchester City hosting Arsenal tomorrow.
Chelsea (4-2-3-1): Cech; Ivanovic, Cahill, Terry (c), F Luis; Matic, Fabregas (Ramires 75); Willian (Schurrle 76), Oscar, Hazard; Diego Costa (Remy 75); unused subs: Courtois, Zouma, Mikel, Salah.
