Fernando Torres scored twice at Sunderland to end his nine-match goal drought and give Rafael Benitez his first Barclays Premier League win in charge of Chelsea.
The Spain striker scored twice in 3-1 win over Sunderland, creating the other Chelsea goal for Juan Mata. Adam Johnson pulled one back for the hosts who drop in to the relegation zone.
Norwich City extended their unbeaten streak in all competitions to 10 matches after beating Swansea City 4-3 at the Liberty Stadium. Steven Whittaker, Sebastien Bassong and Grant Holt gave Norwich a 3-0 half-time lead, but Swansea hit back through Michu and Jonathan de Guzman after the break. Robert Snodgrass calmed the nerves of the away support with the Canaries' fourth before Michu scored the hosts' third at the death.
Mikel Arteta scored two penalties as Arsenal returned to winning ways with a 2-0 victory against West Bromwich Albion.
A second-half strike from James McCarthy denied Queens Park Rangers their first win of the season as Wigan Athletic fought back to draw 2-2 at the DW Stadium. Ryan Nelsen equalised McCarthy's first-half opener to make it 1-1 at half-time, but Djibril Cisse raised away hopes when he put the visitors ahead after 71 minutes. The lead lasted barely two minutes, though, as McCarthy converted Jean Beausejour's pass.
Southampton climbed out of the relegation zone after edging past Reading 1-0 at St Mary's Stadium. A tight contest was decided just after the hour when Nathaniel Clyne found Jason Puncheon and he beat Adam Federici to earn a win that pulls Saints up to 15th.
Aston Villa are now two points above the relegation zone after they could only register a 0-0 home draw against Stoke City, who lost Ryan Shotton to a second yellow card late on.
