The West London side lead the rest by just a solitary point, per BBC Sport.
As the midweek fixtures were decimated by the inclement weather sweeping across the UK, Chelsea's draw at West Brom was enough to see them extend their advantage.
Arsenal could only manage a draw against a staggering Manchester United team, who managed to defensively contain the Gunners at the Emirates to earn a point, and almost took all three.
So who will take the advantage in Week 27? Here is a list of all the fixtures and score predictions:

Chelsea v Everton
Chelsea take on a buoyant Everton side in the early kick-off on Saturday.
It has been a wonderful start for Roberto Martinez to his reign on Merseyside, with his team still very much in contention for the last Champions League position.
However, the Toffees have slipped to 11th in the Premier League form guide after winning just two of their last six matches. Their away record also reads poorly, with the club only managing six points from a possible 18 on the road.
Chelsea on the other hand are flying high and are undefeated in the league since losing away at Stoke on Dec. 11. Per Squawka, the Blues are now on an undefeated streak of 11 games, having played both Arsenal and Liverpool in that run of matches.
It is difficult to see anything but a win for Mourinho's men, as their credentials of Premier League champions begin to grow.
This is the time of the season where the Portuguese manager comes into his own, showing his ruthless ability to close in on titles and grab whichever silverware he desires.
Everton have overachieved this season and the core quality of their football has improved under their new manager.
But Stamford Bridge will be a bridge too far. Chelsea should power on through the gears and dispose of their opponents with ease. The scoreline might remain tight, but it should be a comfortable win nonetheless.
Prediction: 2-1
Liverpool v Swansea

As a Swansea side without Michael Laudrup looks to the future and tries to maintain its Premier League status, the country's form side looks to extend its wonderful run.
Liverpool are top of the form guide with 16 points accumulated from their past six home matches.
The combination of Luis Suarez and Daniel Sturridge with a cast of many have propelled the Reds into not only Champions League contention, but for the English league title as well.
Swansea really do not have a chance at Anfield. Any positive result achieved by them would be a titanic shock especially as Brendan Rodgers' side has destroyed all comers on their own turf.
The Swans are up to 10th in the Premier League table but still only lie four points off the relegation zone.
If Suarez is in the mood it could well turn into a cricket score, but I think the team from South Wales will show some backbone and manage to restrict Liverpool despite losing.
Prediction: 3-1
Crystal Palace v Manchester United
Who knows what the score of a Man Utd match will be these days?
In years gone by a trip to Selhurst Park would not concern United one bit, but in these times of trouble, and with Tony Pulis' team's amazing home form, this could be yet another hard day for David Moyes.
Palace are above United in the form guide and that fact alone is a damning statistic to the reigning league champions.
Palace have won four of their last six games at home, with an unusual slip-up against Newcastle, who beat the Eagles 3-0.
Moyes' side have looked more comfortable away from Old Trafford, and a competent showing away at Chelsea will have delivered some confidence.
But you can't help but feel that some more bad days are still to come.
Palace will have enough to hold a United team yet to find its genuine scoring boots.
One day soon United will click, and the magic of Robin van Persie, Wayne Rooney and Juan Mata will destroy an opponent. However, it will not be against Palace. Pulis has the experience to deal with this United side, and his team will be looking for a counter-punch victory over the Red Devils.
Prediction: 1-1
