LONDON - Unbeaten Chelsea put its off-field concerns aside to beat Norwich City 4-1 at Stamford Bridge yesterday and open up a four-point lead at the top of the Premier League.

Champion Manchester City climbed into second place after preserving its unbeaten record with a 3-0 home win over previously unbeaten Sunderland, while Everton slipped a place to to third after drawing 2-2 at lowly Wigan Athletic.

West Bromwich Albion maintained its surprisingly good start to the season and ended the day in fourth spot when Steve Clarke's side beat Queens Park Rangers, managed by his old Chelsea team mate Mark Hughes, 3-2 at The Hawthorns.

QPR stayed bottom without a win and with just two points while West Brom have now won its first four top flight home games for the first time since the 1919/20 season when it won its only Englsh championship.

Arsenal came from behind to beat West Ham United 3-1 and climb to fifth after Frenchman Olivier Giroud scored his first goal since a close season move from Montpellier while Theo Walcott and Santi Cazorla struck in the last 13 minutes.

European champion Chelsea made headlines for all the wrong reasons in the morning newspapers after Friday's publication of the findings of an FA hearing that questioned the accounts given by skipper John Terry and defender Ashley Cole in the racism case involving Queens Park Rangers defender Anton Ferdinand.

Terry, facing a four-match ban and 220,000 pounds ($356,200 ) FA fine for his racial slur against Ferdinand last year, and Cole, whose evidence was questioned in the 63-page written document, both played against struggling Norwich.

In addition, Cole will face disciplinary action from the club for a foulmouthed Twitter rant against the English Football Association, manager Roberto Di Matteo said yesterday.

Norwich took a surprise lead through Grant Holt after 11 minutes, but Chelsea, playing with style and panache, replied four times with goals from Fernando Torres, Frank Lampard, Eden Hazard and a superb volley from Branislav Ivanovic.
