Arsenal Arsenal returned to the top of the Premier League on Sunday after Jack Wilshere rescued a point for them in a 1-1 draw at West Bromwich Albion, while rivals Tottenham Hotspur suffered a shock 3-0 thumping by West Ham United.
Chelsea relied on two goals in two minutes by substitutes Eden Hazard and Willian late in their match at Norwich City to give them a 3-1 win that lifted them to third in the league with 14 points from seven games, two behind Arsenal and Liverpool.
A week after stunning champions Manchester United 2-1 at Old Trafford, West Brom were up to their old tricks against visitors Arsenal as they took a 42nd-minute lead with Claudio Yacob's powerful downward header.
After somehow escaping further damage from more West Brom chances, Arsenal drew level in the 63rd minute when Jack Wilshere made up for his poor performance until that point when he smashed in a deflected shot from 20 metres out.
The point, which put Arsenal ahead of Liverpool on goals scored, will be all the sweeter for Arsene Wenger's side on a day their bitter north London rivals Tottenham lost ground on the leaders after a mauling by West Ham at White Hart Lane.
Second-half goals from Winston Reid, Ricardo Vaz Te and Ravel Morrison, whose was a superb individual effort after picking the ball up in his own half, secured only a second league victory of the season for Sam Allardyce's side.
There was a heavy police presence inside the ground as part of a crackdown on racism.
In last year's fixture, abuse by West Ham fans put the spotlight back on the the anti-Semitism faced by supporters of Tottenham, which has a strong Jewish fan base.
Police threatened to take action against anyone who chanted ''Yid,'' even if it was Tottenham supporters who use the term affectionately to deflect anti-Semitic abuse. But the term, often used as a derogatory term for Jews, was sung with gusto by Tottenham fans and there was no sign of any mass arrests.
The Metropolitan Police said immediately after the game that it only had details of one man being arrested
