FRANK Lampard scored his fourth goal in a week as Manchester City beat Hull City in the Premier League.
City had taken a two-goal lead after Sergio Aguero's volley and an Edin Dzeko strike from distance.
But City's Eliaquim Mangala headed into his own net, then conceded a penalty, from which Abel Hernandez made it 2-2.
However Dzeko struck again from close range, then substitute Lampard hit his fourth goal in a week to secure the 4-2 win.
Wayne Rooney scored and was sent off as Manchester United beat West Ham United 2-1.
The home side were cruising after Rooney swept in a Rafael cross and Robin van Persie rifled in a low shot.
But Diafra Sakho nodded in for the Hammers before Rooney was sent off for a reckless tackle on Stewart Downing.
Enner Valencia shot wide and Kevin Nolan had an effort ruled out for offside as the home side held on.
Phil Jagielka's spectacular injury-time equaliser earned Everton an unlikely Premier League point in the 223rd Merseyside derby.
It had appeared Steven Gerrard's superb second-half free-kick would give Liverpool victory until Jagielka's scorching, swerving shot into the top corner from 30 yards stunned the home fans.
Diego Costa's outstanding start to his career at Chelsea continued as he grabbed his eighth goal to help the leaders to a 3-0 victory against Aston Villa.
Two goals in the space of three second-half minutes gave Crystal Palace their first home win of the season with victory over Leicester City while QPR's dire Premier League away record continued as they lost to a Southampton team celebrating a fourth successive league victory.
The hosts, enjoying their best start to a top-flight season, were the better side with Dusan Tadic hitting a post.
Ryan Bertrand gave Southampton the lead, drilling low beneath Robert Green, before Charlie Austin levelled with a superb volley on the turn.
But Graziano Pelle's stunning scissors kick clinched the win.
The Italian striker's fifth goal of the season ensured Southampton recorded a sixth successive victory in all competitions, and kept them second in the league, three points adrift of leaders Chelsea.
Elsewhere, Sunderland and Swansea drew 0-0.
