Chelsea strolled to perhaps their best win of the season to date with a 5-0 thrashing against Swansea City at the Liberty Stadium.
Oscar got the party started nice and early by scoring in the first minute thanks to a sweet strike from the edge of the area that arrowed into the corner of the net.
Chelsea on fire
That set the tone for the rest of the game and Diego Costa bagged his 16th goal of the season to effectively put the game to bed well before half-time. That goal also marked Cesc Fabregas' 15th assist this season.
Costa added his second, as did Oscar, in the space of two minutes with 10 minutes still to go before half-time. Chelsea strolled around the pitch in the second-half and eventually added a fifth through Andre Schurrle with 78 minutes gone.

It took some good work from Antonio Valencia on the wing to find Marouane Fellaini in the box, and the Belgian smashed home from 12 yards. James Wilson rounded things off with his first Premier League goal in extra time to seal a key win for the Red Devils.
Spurs see off Black Cats
That's exactly what Tottenham managed, a key win, too as they fought to a 2-1 victory over Sunderland at White Hart Lane. Mauricio Pochettino's side got off to a quick start and took the lead through Jan Vertonghen who showed some quick feet in the box before firing home early on.
The home side looked to be flying but were pegged back thanks to a wonderful free-kick from Seb Larsson after Vertonghen had bought down Jermain Defoe around 25 yards from goal.
Tottenham emerged much the better team after half-time but just couldn't find the back of the net - only for that man Christian Eriksen to strike late on to save Spurs' blushes.
Elsewhere in the Premier League, Crystal Palace rounded off an unbelievable fightback from 2-0 down to claim a 3-2 win, with Dwight Gayle scoring the decisive goal.
Liverpool were comfortable 2-0 winners against Aston Villa thanks to efforts from Fabio Borini and Rickie Lambert, while a moment of magic from Bojan helped Stoke beat Leicester 1-0.
