Chelsea take on Arsenal in a battle of the top three at Stamford Bridge on Saturday, with the hosts looking to bounce back from their 1-0 defeat at Aston Villa.
The Gunners will be full of confidence as they travel across London, having battled to a 1-0 derby win over Tottenham in their last outing.
Arsene Wenger's men sit four points adrift of the table toppers—alongside Liverpool—with both clubs holding a game in hand over Jose Mourinho's side.
A win for Chelsea would restore their seven-point lead over Arsenal and maintain pressure on Manchester City, who remain in pole position with three games in hand.

Can Arsenal End Mourinho's Unbeaten Run?
If Arsenal are to close the gap on Chelsea, they will have to tread on uncharted waters and defeat Mourinho at the Bridge.
For 75 league matches and counting, a Mourinho-led side has not lost at Stamford Bridge. Match of the Day tweeted of the task Chelsea's visitors face in west London:
The Portuguese manager first joined the club in June 2004 and, with home comforts, has faced Arsenal on three league occasions—winning once and drawing twice, per SoccerBase.com.
The last encounter came on Dec. 10, 2006, when Michael Essien's 84th-minute strike ruled out Mathieu Flamini's opener to snatch a 1-1 draw.
If the Gunners are to win, they will have to muster a similar resolve as seen at White Hart Lane last time out.
Tomas Rosicky's goal after just 72 seconds set the match up, after which the Gunners showed their defensive prowess as they bolstered their hunt for a first title in 10 years.
Olivier Giroud has bagged 12 league goals this season, per WhoScored.com, and looks set to once again start as a lone striker for the Gunners.
Therefore, Arsenal's midfield will have to be as explosive as seen against Spurs, with the likes of Rosicky willing to take on goalscoring responsibilities.
For Chelsea, Ramires and Willian are both suspended, so Mourinho isn't at full strength in a game neither side can really afford to lose.
Can Samuel Eto'o Score Again?
Eto'o has proved he is the man to score big goals at important times for Chelsea. His strike against Galatasaray in the Champions League set the Blues on their way into the quarter-finals:
As highlighted by WhoScored, the Cameroon forward has popped up on seven occasions for Chelsea in the league this season.
Amongst those, he opened the scoring in the Blues' 4-0 win over Spurs, as well as netting a hat-trick against Manchester United at the Bridge.
He also scored the eventual winner in the 2-1 home victory over Liverpool and bagged two goals in the Champions League to see off Schalke.
Mourinho had questioned the striker's age earlier this season, with Eto'o responding in turn with an apt celebration after scoring against Spurs, per Daily Mail's Gerry Cox.
The pair will look to continue their flourishing relationship with the visit of Arsenal, as Eto'o tussles with Fernando Torres for a starting spot.
Demba Ba could also feature against the Gunners, the club he dismissed talk of joining in January, per Sky Sports' Pete O'Rourke. Ba is looking for only his fourth league goal of the season after being used primarily from the bench, per WhoScored.
However, given Eto'o's form of late, he looks most likely to lead the line against Wenger's men, and given previous strikes against the Premier League's top clubs, you'd back him to do the same again.
Arsenal arguably have the harder run-in of the two sides, with matches against Manchester City and Everton, as well as matches against survival-scrapping Swansea and Hull.
Meanwhile, Chelsea take on Liverpool with the rest of their matches against sides in the bottom half of the table.
The Blues need victory against the Gunners to keep hold of the top spot, and with City harbouring three matches in hand, Mourinho's men need to make each victory count if they are to regain the title.
