Jack Wilshere rescued a point for Arsenal at West Brom to send them level with Liverpool at the Premier League summit, but a thrilling match might easily have gone either way.
The Baggies, fresh from downing Manchester United last weekend, had ample opportunity to extend their lead after Claudio Yacob headed home a Morgan Amalfitano cross in the 42nd minute.
But it was Arsenal who ended the game in the hunt for the points after Wilshere, looking to replace reports of late night smoking with more positive headlines, scored with a deflected first-time shot from 20 yards to grab a 1-1 draw.
Tottenham suffered their biggest home defeat of Andre Villas-Boas’ reign as West Ham ran riot with a stunning second-half display at White Hart Lane. The Hammers scored three stunning goals in 13 minutes to come away with their first victory at White Hart Lane since 1999.
Winston Reid started the rout with a goal from a corner, Ricardo Vaz Te made doubled the lead and then Ravel Morrison scored a superb solo strike to seal the 3-0 win.
Substitutes Eden Hazard and Willian were on target as Chelsea beat Norwich 3-1 to claim a first away win of the league campaign. Chelsea made a flying start when Oscar gave them a fourth-minute lead after Demba Ba’s lay-off from Frank Lampard’s lofted pass.
Victory from then seemed a formality for Chelsea but it appeared anything but until a late rally. Adam Lallana and Jay Rodriguez strikes secured Southampton a third successive league victory, albeit in somewhat fortuitous fashion against Swansea.
The clash between two sides known for their attractive style lived up the billing, with play flowing from end to end in a pulsating encounter at St Mary’s. Swansea dominated proceedings after Lallana’s first-half strike, only for substitute Rodriguez to make the most of slack defending to secure a 2-0 win for Mauricio Pochettino’s side.
