LONDON - Jack Wilshere has sent Arsenal back to the top of the Premier League table with a second-half equaliser in an entertaining 1-1 draw at West Bromwich Albion.
Bidding to follow up last weekend's shock victory at Manchester United, West Brom took a 42nd-minute lead at The Hawthorns on Sunday when Claudio Yacob converted Morgan Amalfitano's right-wing cross with a near-post header.
Tottenham Hotspur could have moved level on points with the leaders, but they were dealt a stunning 3-0 home defeat by London rivals West Ham United.
The result leaves Spurs in sixth place, three points below Arsenal and Liverpool, while West Ham leap out of the bottom three to 13th.
Earlier, Eden Hazard and close-season signing Willian came off the bench to score decisive goals as Chelsea won 3-1 at Norwich City to climb to third place.
The visitors took a fourth-minute lead when Oscar drilled home from Demba Ba's lay-off, but Norwich gradually took the upper hand and equalised in the 68th minute. Southampton continued their fine start to the season by winning 2-0 at home to Swansea City, which sent Mauricio Pochettino's side to the dizzying heights of fourth place.
