David Silva scored a late goal as runaway leaders Manchester City won their 13th successive Premier League game and restored their eight-point lead with a 2-1 victory against West Ham United.
Silva converted Kevin de Bruyne's brilliant pass from close range in the 83rd minute as City maintained their blistering form this season.
Nicolas Otamendi had converted substitute Gabriel Jesus's cross in the 57th minute to equalise after defender Angelo Ogbonna had headed West Ham into the most unlikely lead at the end of a first half in which the hosts dominated.
City have not lost a game since April, and face second-place rivals Manchester United next Sunday. West Ham, who have won only twice all season, sit 19th - three points behind West Bromwich Albion in 17th.
Earlier, Southampton's Charlie Austin was on target again as the Saints drew 1-1 with south coast rivals Bournemouth.
Bournemouth's Ryan Fraser curled home the opener in the 42nd minute of an even first half after Southampton defender Wesley Hoedt was guilty of overplaying and was dispossessed by Joshua King.
Southampton began to dictate proceedings after the break and the in-form Austin - who scored a brace against Everton last weekend - restored parity with a smart finish from substitute Nathan Redmond's low cross in the 61st minute.
Austin, who has scored seven goals in his last 10 league starts, twice had chances to win it for Southampton while Bournemouth substitute Callum Wilson was unable to control a loose ball with the goal at his mercy.
"Going in at halftime 1-0 down we were not good enough in the first half but we stepped up in the second and looked like we were going to nick it," Austin told Sky Sports.
"Instead it's a point away from home going into a big December. I should have scored a near-post header but these things happen. I was still in the right place at the right time.
"I've just got to score goals, work hard and help us win games. We've got a lot of big games coming up."
Southampton climb one place to 11th with 17 points, two points and three places above Bournemouth.
