(CNN) -- Chelsea continued their unbeaten start to the English Premier League season with a 2-1 win against north London rivals Arsenal at the Emirates Stadium on Saturday.
Goals from Spanish duo Fernando Torres and Juan Mata earned the Blues a fifth win in six league matches while handing Arsene Wenger's men their first League defeat this term.
Torres put Chelsea ahead in the 20th minute hooking the ball past Mannone in the Arsenal goal after some sloppy defending by the home side.
But the Gunners were back on level terms three minutes before the break when Gervinho guided the ball past Petr Cech after latching on to Alex Oxlade-Chamberlain's cross.
Mata's decisive goal came eight minutes into the second half -- his free-kick deflecting off Laurent Koscielny before finding the bottom corner of the net.
Chelsea now have 16 points and remain top of the league while Arsenal slip to seventh on nine points.
The win was a satisfying end to another turbulent week for John Terry.
The Chelsea captain announced his retirement from international football on Sunday, before being handed a four-match ban and a £220,000 ($356,000) by the English Football Association (FA) on Thursday for racially abusing Queens Park Rangers defender Anton Ferdinand during a match in October 2011.
A court cleared Terry of the same offense in July, but the FA requires a lower burden of proof. Terry is currently considering whether to appeal the ban.
Elsewhere, Tottenham Hotspur recorded their first win at Old Trafford in 23 years as Andre Villas Boas's side beat Manchester United 3-2.
Defender Jan Vertonghen put Spurs ahead in the second minute before Garath Bale doubled the lead half an-hour later.
Nani halved the deficit six minutes after the break only for Clint Dempsey to restore the two-goal cushion two minutes later.
But United responded immediately as Shinji Kagawa made it 3-2, which, despite the home side's effort was how the score stayed.
Alex Ferguson's men are now third with 12 points, level with Manchester City who had Edin Dzeko to thank for their 2-1 win against Fulham at Craven Cottage.
Mladen Petric blasted home a penalty to put the Cottagers ahead in the 10th minute after Pablo Zabaleta had brought down John Arne Riise.
Sergio Aguero equalized for City two minutes before halftime with Dzeko scoring the winner in the 87th minute, moments after coming on for Francisco Javi Garcia.
Everton continued their promising start to the season with a 3-1 over Southampton at Goodison Park.
A goal from Leon Osman (25th minute) and a quickfire brace from Nikica Jelavic (32nd and 38th minute) earned three points for David Moyes' team after Gaston Ramirez had given Southampton the lead in the sixth minute.
Everton remain three points behind leaders Chelsea.
Merseyside rivals, Liverpool posted their first league win under new manager Brendan Rodgers with a 5-2 thrashing of Norwich City.
Luis Suarez scored a hat-trick as the Reds ran riot at Carrow Road with Nuri Sahin and Steven Gerrard also getting on the scoresheet. Steve Morison and Grant Holt made the scoreline look a bit more respectable with two second-half goals.
Liverpool rise to 14th, Norwich slip to 18th in the table.
