In Monday's late kick-off at Molineux, Carlos Tevez scored twice as Roberto Mancini's first away game in charge of Manchester City ended in a 3-0 win over Wolves. Javier Garrido scored the other goal from a free-kick.
Tottenham moved up to fourth spot, and within three points of United, with a 2-0 win over West Ham at White Hart Lane, thanks to goals from Luka Modric and former Hammer Jermain Defoe. On-song Birmingham, meanwhile, made it a club record 11 games unbeaten as Cameron Jerome struck the only goal of the game at Stoke.
Further down the table, Burnley's away-day blues continued with a 2-0 defeat at Everton, brought about by second-half goals from James Vaughan and Steven Pienaar, while Darren Bent's double for Sunderland was cancelled out by goals from Blackburn's Morten Gamst Pedersen and El-Hadji Diouf.
