LONDON - Arsenal crashed to its fourth loss of the Premier League season at Tottenham while Frank Lampard's hat trick helped Chelsea rout Bolton on Sunday.
Rafael van der Vaart and Kyle Walker secured Tottenham's 2-1 derby victory over Arsenal, which is just two points above the relegation zone after seven matches.
Chelsea is third in the standings after Lampard proved his enduring value to the club in a 5-1 victory at bottom-place Bolton, having regained his place in the team.
There was also a hat trick at Fulham for Andy Johnson as Queens Park Rangers was thrashed 6-0, while promoted Swansea beat Stoke 2-0 in Sunday's other game.
The weekend ended with Manchester still in control of the league, with United only ahead of City on goal difference after they both won on Saturday.
And after seven games, Arsenal is already 12 points behind United and City, languishing just two points above the relegation zone.
"To say today we will win the league is not realistic," Arsene Wenger said a day after marking 15th years as Arsenal manager. "If we get in a better position (maybe)."
Arsenal conceded five minutes before half time when Van der Vaart scored the 10,000th goal in Tottenham's history, according to the club.
But Wenger claimed Van der Vaart used his arm — rather than chest — to bring down Emmanuel Adebayor's cross before striking into the bottom corner.
Aaron Ramsey levelled for Arsenal six minutes after the break, dispatching the ball into the net after Van der Vaart failed to close down Alex Song on the left flank.
But after Song blocked a shot from Luka Modric at the other end in the 73rd, the ball fell to Walker, who unleashed a swerving, dipping shot that went through goalkeeper Wojciech Szczesny's hands.
Tottenham's fourth straight win after starting the season with losses to the Manchester clubs puts Harry Redknapp's sixth-place side seven points behind the leaders with a game in hand.
Chelsea is just three points behind the pacesetters in third.
Daniel Sturridge set the tone for Chelsea's emphatic win at Bolton by heading in a second-minute opener before setting up Lampard to score his first.
Two errors in quick succession by Bolton goalkeeper Adam Bogdan allowed Lampard and Sturridge to each score again.
The Hungarian let Sturridge's shot from the edge of the box loop in off him when he should have saved it. Lampard buried his second after David Luiz's strike was parried straight to the midfielder.
Dedryck Boyata had given bottom-place Bolton a faint hope of a comeback at 4-0 with a 46th-minute headed goal, but Didier Drogba set up Lampard's third.
"It was good for him because he had a good, solid performance alongside the rest of the team," Chelsea manager Andre Villas-Boas said about Lampard. "He arrived with perfect timing into the box as he has done in the past years. His talent was never in question."
At Craven Cottage, Fulham moved two points clear of the drop zone thanks to Andy Johnson's treble, with the first coming after just two minutes.
Johnson followed up by winning a penalty that was converted by Danny Murphy, before turning home a cross from Bobby Zamora before half time and bringing up his hat trick just before the hour mark.
Zamora then set up Clint Dempsey, who returned the favour for his strike partner to score the sixth.
In south Wales, Scott Sinclair put Swansea ahead from the penalty spot after Stoke captain Ryan Shawcross' rash challenge on Wayne Routledge.
And Danny Graham fired home his first goal for Swansea since moving from Watford for a club-record 3.5 million pounds (US$5.7 million).
