LONDON (AP):Manchester United were toppled from the Premier League summit by Manchester City yesterday after losing to Norwich, while their cross-town rivals routed Aston Villa to top the standings for the first time this season.

United's third loss of the season was inflicted by former youth team player Anthony Pilkington, whose second-half header gave Norwich a 1-0 win.

Defending champions City moved a point ahead of United after recording the biggest win of the season, beating Villa 5-0 as Sergio Aguero and Carlos Tevez each scored twice after David Silva's opener.

In a day of a drama, third-place Chelsea lost 2-1 as manager Roberto Di Matteo returned to former club West Bromwich Albion, who moved a point behind the European champions.

And in the north London derby, Arsenal came from behind to beat Tottenham 5-2 after Emmanuel Adebayor's sending off swung the game in his former team's favour.

The pressure increased on Queens Park Rangers manager Mark Hughes after his winless side lost 3-1 to Southampton to stay bottom. But Reading secured their first win, beating Everton 2-1, while Luis Suarez scored twice in Liverpool's 3-0 win over Wigan and Swansea won 2-1 at Newcastle.

LACKLUSTRE DISPLAY

At Carrow Road, it was a lacklustre display from United, who were without striker Wayne Rooney because of tonsillitis. Norwich secured their third win in five league matches when Pilkington headed in Wes Hoolahan's cross on the hour.

City remain the only unbeaten team and finally looked like title contenders again yesterday.

But City took until the 43rd minute to take the lead, with Silva tucking the ball into the net from close range after Villa failed to deal with Samir Nasri's corner.

"In the first half, we played well, created a lot of chances, but we were too soft when we had chances to score," Mancini said.

City were far more ruthless after the break, with Aguero netting from the spot in the 54th after Andreas Weimann handled.

City were awarded another penalty 10 minutes later when Barry Bannan handled and Tevez converted his spot kick.

Aguero was on target again, with the Argentina striker scoring from a tight angle after bursting into the penalty area.

Tevez completed the rout by grabbing his second, tapping in from close range after being picked out by Nasri. The result plunged Villa into the relegation zone.

Chelsea had been in control of the Premier League in the opening weeks but have slipped to third and are on a four-game winless run.

LONG FINDS NET

Shane Long put West Brom in front a day after his grandmother died and revealed an "RIP Nan" T-shirt after heading in James Morrison's cross in the 10th.

Eden Hazard levelled before half-time, heading in his fourth goal of the season, but Peter Odemwingie nodded in West Brom's winner after the break from Long's cross.

At Emirates Stadium, Adebayor put Tottenham in front after 10 minutes but was sent off eight minutes later for a high challenge on Santi Cazorla.

Per Mertesacker started Arsenal's comeback with a 24th-minute header, and Lukas Podolski and Olivier Giroud both found the net before half-time.

Cazorla swept in the fourth goal on the hour before Gareth Bale reduced the deficit for Tottenham, but Theo Walcott knocked in the fifth in stoppage time to give Arsenal a lift after their worst start to a season since during Wenger's 16-year reign.

A third successive league loss for Spurs allowed Arsenal to move above Tottenham into sixth.
