On Sunday, two of the Premier League's most storied clubs will take the pitch at Stamford Bridge, as Arsenal takes on Chelsea FC in a pivotal midseason match.
The Blues won the two teams' first meeting of the year, defeating the Gunners at Emirates Stadium in September, but since then, things haven't gone according to plan for either team.
Both clubs entered the season expecting to at least contend for the Premier League crown, but as it stands, neither are within 14 points of first-place Manchester United and remain a sizable distance from Manchester City as well.
Both clubs have world-class talent, and with so much at stake, it should be a very entertaining showdown on Sunday.
Here's everything you need to know to tune in for this all-important match.

What's at Stake?
Thus far, the Gunners have endured a disappointing season and enter the weekend outside the Champions League and Europa Cup berths in sixth place, but they'll get an opportunity to change that, as they take on the third-place Blues on the road.
For Chelsea, the match will be a critical one for Rafael Benitez's men, as the Blues sit just one point ahead of Tottenham Hotspur for the third Champions League berth, and a loss would significantly hurt their chances at qualifying at all.
The Blues obviously have a much better chance at catching Manchester City, but for Arsenal, who could be facing some big changes during the next transfer window, a win over a top-flight opponent would be a nice consolation prize.
Player to Watch for Arsenal: Theo Walcott
Since the season began, the questions surrounding Theo Walcott's future at Arsenal have persisted—until this week, when The Telegraph reported that the star striker had reached an agreement on a "new three-and-a-half-year contract with the club in a deal that is understood to be worth £20 million."
Now, the pressure will be on the England international to live up to his hefty contract, because the deal indicates that Arsene Wegner considers Walcott to be a key to the Gunners' offense for the next few seasons.
So far this season, Walcott has been reasonably impressive, with 14 goals in 26 total matches, but in order to satisfy the supporters at Emirates Stadium, he'll have to be more of a game-changer, and that starts with bagging his first goal of 2013.
Player to Watch for Chelsea: Demba Ba
Ba has been very impressive since leaving Germany in 2011 and should be an upgrade for Chelsea offensively, as he's already found the back of the net 15 times this season.
The real challenge for Ba may be whether or not he can get Fernando Torres to start scoring like he did prior to arriving at Stamford Bridge.
This match features two underachieving Premier League heavyweights who will be desperate for points, but Arsene Wegner's Gunners will be hungry to avenge the loss they were dealt at home earlier this season.
Both clubs have struggled against elite teams, and with the Blues coming off a disappointing draw against Southampton, Theo Walcott, with his new contract in hand, will lead the Gunners to victory.
