Manchester City's hopes of a maiden English Premier League football title have taken another hit, after having to come back to draw 3-3 at home to Sunderland.
City salvaged a point with two late goals but the result helps tip the balance in the title race more in Manchester United's favour.
Sunderland ended City's perfect home record with two goals from Sebastian Larsson and one from Niklas Bendtner, halting their run of 15 straight home league wins this season.
The visitors led 3-1 with five minutes to play before Mario Balotelli, who also scored a first-half penalty, pulled one back after 85 minutes and Aleksandar Kolarov saved a point a minute later.
United, who play Blackburn Rovers at Old Trafford on Tuesday, lead the standing with 73 points, City are second on 71.
Lowly Queens Park Rangers ended Arsenal's seven-match winning league run with a 2-1 victory at Loftus Road.
Chelsea won 4-2 at Aston Villa to move within two points of fourth-placed Tottenham Hotspur who play Swansea City on Monday.
Wolves are six points adrift at the bottom on 22 points after losing 3-2 at home to Bolton Wanderers who moved on to 28 points. They have the same as QPR and Wigan Athletic, who beat Stoke City 2-0.
