Arsenal will still enter Week 12 as the Premier League's top squad, but their lead shrunk after falling 1-0 to Manchester United on Sunday.
The Gunners now see six teams within five points of them. Liverpool could seize at least partial possession of first next week with a win and an Arsenal loss or draw.
While Arsenal and Manchester United's marquee match hogged most of the attention, three other bouts filled the Sunday scope. Sunderland and Newcastle notched 1-0 victories of their own, while Swansea City and Stoke City battled to a high-scoring draw.
Here's an updated look at how the table looks entering Week 12:
Manchester United 1, Arsenal 0
Robin van Persie delivered a slice of revenge against his old team, scoring the only goal in Manchester United's victory over Arsenal.
The Dutch striker, who played with Arsenal for eight seasons before jumping ship to United in 2012, netted a goal in the 27th minute on a Wayne Rooney corner kick. Van Persie now has seven goals in Premier League play this season.
Arsenal controlled possession, but they were unable to capitalize on any of their scoring chances. The loss marks the second time they were held off the scoresheet this season.
United jumps ahead to fifth place with the win, while Arsenal holds a two-point lead over Liverpool.
Sunderland 1, Manchester City 0
Sunderland entered Sunday's match with one win and four points, putting them in a tie for last place with Crystal Palace. So a matchup against Manchester City did not look very promising.
Shockingly, Sunderland pulled off a stunning upset, shutting out City in a 1-0 victory that pulled them out of last place.
Phil Bardsley scored the match's only goal to give his club their fourth straight home victory over City—a head-scratching feat that drops the losing squad to eighth despite boasting the league's best goal differential.
Even Gus Poyet looked surprised that his club won.
Sunderland now possesses a reasonable shot at escaping relegation's grasp, as they trail No. 17 Stoke City by three points.
Newcastle 1, Tottenham 0
Newcastle rejected Totthenham's plans to jump back into the top four with a narrow victory.
While Spurs attacked throughout the match, goalkeeper Tim Krul prevented them from finding the net. The star keeper collected a career-high 14 saves, a mark that the Premier League's Twitter page said has not been touched in years.
Loic Remy produced his seventh goal in Premier League play to break the stalemate for Newcastle, who yet again took down a top opponent.
The win helps Newcastle climb to ninth, but the league's elite should fear the grouping's giant slayers. Newcastle has now collected victories over Tottenham and Chelsea in a two-week span after drawing with Liverpool earlier in the year.
Swansea City 3, Stoke City 3
Swansea City and Stoke City each tallied as many goals as the day's other six competing squads combined. Yet it was not enough for either club to walk away with three points.
Swansea nearly had the win, but Charlie Adam delivered a late goal during stoppage time to save a point for the Potters.
It took remarkable efficiency for Stoke to escape with a draw. Per the Premier League's Twitter page, the squad converted on all three of their shots on target to avoid leaving empty-handed.
The crucial point keeps Stoke out of relegation, while Swansea squandered a chance to jump into a four-way tie for 10th place, instead settling in at No. 13 with 12 points.
