LONDON — Premier League leader Chelsea beat London rival Arsenal 2-1 with goals from Spaniards Fernando Torres and Juan Mata Saturday to maintain its unbeaten start to the season while handing Arsenal its first defeat. Liverpool recorded its first league win at the sixth attempt with an emphatic 5-2 victory at Norwich City with Luis Suarez scoring a hat trick after also scoring three at Carrow Road in April. Nuri Sahin and Steven Gerrard scored Liverpool's other goals. Champion Manchester City, without a win in any competition for four games, came from behind to win 2-1 at Fulham with a late winner from substitute Edin Dzeko only a minute after coming on. Everton maintained its good start to the campaign, coming from behind to beat Southampton 3-1 with all its three goals coming in 13 first-half minutes with Nikica Jelavic scoring twice. In the other games, Stoke City won for the first time this season and sent Swansea City to a third successive defeat with Peter Crouch scoring both in its 2-0 win on his 500th league appearance. Sunderland also won for the first time this season after four straight draws with Steven Fletcher, the only player to score for it in the league so far, grabbing the winner in its 1-0 win over Wigan Athletic who had Jordi Gomez sent off. Reading was denied its first win after going 2-1 up against Newcastle United when Demba Ba appeared to secure the equalizer and his second goal in a 2-2 draw with his arm. Reading climbed one place off the bottom to 19th while Queens Park Rangers, who play West Ham on Monday, slipped to last. There was no doubting the legality of either of Chelsea's goals from Torres and Mata. Both came as a result of Mata free kicks and poor Arsenal defending with Torres out-muscling Laurent Koscielny to volley the European champion ahead after 20 minutes for his third league goal of the season. Gervinho equalized for Arsenal three minutes before the break when he turned crisply and fired into the roof of the net for his fourth goal of the campaign. Chelsea, which started with skipper John Terry as he mulls an appeal over a four-game ban for racist abuse, went back in front after 53 minutes when Mata's free kick eluded everyone before clipping Koscielny and flying in past stand-in keeper Vito Mannone. Chelsea manager Roberto Di Matteo told Sky Sports: “I thought we were excellent today and deservedly won the game.” Liverpool, making its worst start to a league season for 101 years, finally won for the first time after coach Brendan Rodgers fielded a young side including teenagers Suso, Raheem Sterling and Andre Wisdom. But it was old campaigner Suarez who showed them all the way with a second hat trick at Carrow Road after scoring all the goals in Liverpool's 3-0 win there last April. Norwich was booed off at halftime but rallied with replies from Steve Morison and Grant Holt but the defeat left it in 18th place. Manchester City also won away but were made to come from behind at Craven Cottage where Fulham went ahead through a Mladen Petric penalty after 10 minutes. Sergio Aguero equalized just before the break before Dzeko wrapped up the points with an 87th minute winner to lift City into fourth place. — Reuters
