CHELSEA extended its Premier League lead to four points with a 4-1 win over Norwich on Saturday while champion Manchester City got back on track by crushing Sunderland 3-0.

Roberto Di Matteo's unbeaten Chelsea has made a flying start to its title challenge and this was the European champion's sixth win in seven league matches.

The Blues recovered from the shock of Norwich striker Grant Holt's 11th-minute opener at Stamford Bridge to take complete control before half-time.

Fernando Torres equalised with his fifth goal of the season, the Spaniard heading home from a Branislav Ivanovic cross in the 14th minute.

Frank Lampard put Chelsea in front in the 22nd minute with a drive from the edge of the area and Belgian playmaker Eden Hazard, netting a cool 31st-minute strike from Juan Mata's pass, shattered Norwich's resistance.

Ivanovic rubbed salt into Norwich's wounds when he bagged the fourth goal with 14 minutes left.

Roberto Mancini's Manchester City was ahead after five minutes at Eastlands when Serbian defender Aleksandar Kolarov curled a superb free-kick past Sunderland goalkeeper Simon Mignolet.

Substitute Sergio Aguero got the second goal on the hour and England midfielder James Milner ensured City would move into second place with an 89th-minute free kick that glanced in off Craig Gardner.

Theo Walcott came off the bench to inspire Arsenal as it won 3-1 at London rival West Ham.

Senegal midfielder Mohamed Diame gave West Ham the lead in the 21st minute with a superb individual effort, but the Gunners drew level four minutes before half-time when Olivier Giroud volleyed home Lukas Podolski's cross from close range for his first Premier League goal since his move from Montpellier, in France

Walcott got the crucial second in the 77th minute with a clinical low finish and Santi Cazorla completed the win with a long-range effort from Walcott's pass.

Third-placed Everton salvaged a 2-2 draw at Wigan thanks to a late penalty from former Latics man Leighton Baines.

Wigan went ahead in controversial circumstances when Arouna Kone finished off a fine run from Shaun Maloney, even though the Ivory Coast striker was clearly offside.

Everton hit back one minute later through Nikica Jelavic and, although Franco Di Santo put Wigan back in front in the 23rd minute, Baines fired home from the spot with three minutes to go.

West Bromwich Albion continued its surprising start to the season by climbing to fourth place with a 3-2 victory over bottom-of-the-table QPR at the Hawthorns. Reading blew a great chance to secure its first league victory of the season as Swansea recovered from two goals down to draw 2-2 at the Liberty Stadium.
