Chelsea left it late to clinch a 3-1 victory over ten-man Norwich City in a match that was marred by a serious injury suffered by Didier Drogba at Stamford Bridge.

Andre Villas-Boas's side were in danger of being held to a draw by newly-promoted Norwich when Grant Holt punished a mistake from Blues goalkeeper Hilario to cancel out Jose Bosingwa's opener. Drogba was stretchered off soon after when he landed heavily following an aerial collision with Norwich goalkeeper John Ruddy.

However, Lampard ensured Chelsea won for the second time in three league games under Villas-Boas when he drove home a spot-kick with eight minutes remaining before Juan Mata marked his debut following his move from Valencia with a goal in the final moments.

Liverpool go top
Liverpool moved to the top of the table, above Chelsea and Wolverhampton Wanderers on goal difference, after a 3-1 victory over Bolton Wanderers at Anfield.

Kenny Dalglish's side were on course for their second league win of the campaign from the moment England midfielder Jordan Henderson - a £16 million signing from Sunderland in the close-season - curled home a fine finish in the 15th minute for his first Reds goal.

Martin Skrtel put Liverpool in complete control in the 52nd minute when the Slovakian defender headed home a Charlie Adam's corner. Former Blackpool midfielder Adam then sealed an impressive display for the Reds one minute later when he drilled a low shot past Jussi Jaaskelainen to claim his first goal for the club.

Bolton striker Ivan Klasnic got one back in stoppage time, but it was no consolation for the visitors.

"It was a pleasure to watch," Dalglish said. "We got the result because we worked hard and played for each other. To lose a goal at the end maybe puts a dampener on it for 40 seconds or so, but that also says a lot."

Everton edge Blackburn
Blackburn Rovers missed two spot-kicks and then paid the penalty as Everton secured a 1-0 win at Ewood Park.

Rovers squandered a chance to take the lead early in the second half when Tim Howard saved Junior Hoilett's penalty after Mauro Formica won the spot-kick after contact from Ross Barkley. And Formica missed from the spot himself, shooting against a post after being fouled by Phil Jagielka in the final minutes.

Everton made the hosts pay for those missed chances when Spanish midfielder Mikel Arteta stroked home a 90th minute penalty awarded for a Chris Samba challenge on Marouane Fellaini.

Swansea were held to a 0-0 home draw for the second successive week as Sunderland held firm in a dour struggle at the Liberty Stadium. Wigan Athletic maintained their unbeaten start as a fine double by Argentinian striker Franco Di Santo secured a 2-0 win over Queens Park Rangers.

Wolverhampton remain undefeated with seven points after Mick McCarthy's team fought out a 0-0 draw at local rivals Aston Villa.
