Chelsea's marauding start to the Premier League season continued as they came from behind to thrash Bolton Wanderers 5-1 at Stamford Bridge.

Manchester United moved up to third with a 3-1 victory at Sunderland but Arsenal's problems increased with a 2-1 reverse at West Bromwich Albion that leaves them 14 points off the pace.

Tottenham Hotspur maintained their best ever start to a Premier League season with a 2-0 win over bottom club Everton at White Hart Lane to go second.

Promoted Wigan Athletic also have plenty to celebrate after a 1-0 victory at home to Newcastle United that elevated them to the giddy heights of fourth.

Chelsea's last league defeat came exactly a year ago at Manchester City and, for 45 minutes, Bolton Wanderers looked capable of snapping their 37-game unbeaten league run.

Greek striker Stelios Giannakopoulos silenced Stamford Bridge with a fourth-minute opener and the visitors threatened to add to their tally before the break.

The match turned completely in nine devastating second-half minutes when Didier Drogba and Frank Lampard both scored twice for the champions and Bolton's Ricardo Gardner was red-carded for a deliberate handball on the edge of the area.

Lampard's double took his tally for the week to four after his winning goals against Austria and Poland sealed England's place in next year's World Cup finals.

Eidur Gudjohnsen completed the rout to make it nine wins out of nine for Chelsea in the Premier League this season and keep them nine points in front of London rivals Tottenham.

"I went in early for halftime to prepare what I was going to say to them," Chelsea boss Jose Mourinho, who is yet to lose any match at Stamford Bridge, told Sky Sports.
