Mikel Arteta celebrate after scoring his penalty
Both Arsenal and Chelsea put a bad week behind them with a 2-0 win against West Brom at the Emirates while the Blues beat Sunderland 3-1 at the Stadium of Light.
Bacary Sagna was passed fit and started while Lukas Podolski made the bench, meaning Gervinho and Alex Oxlade-Chamberlain flanked Olivier Giroud up front.
And the Ivorian had the first chance of the game after a corner was half cleared. Jack Wilshere headed it back in, the keeper came, half punched, and it fell for Gervinho who hooked a shot back across goal only to see it drift just wide.
Shortly after, good build up play from Arsenal set up a chance for Santi Cazorla, about 20 yards out, but for once his technique was less than perfect and he skewed it wide. The Spaniard was involved again soon after when Bacary Sagna played a fine ball over the top and down the line for Oxlade-Chamberlain, he raced onto it, fired over a first time cross which Cazorla met on the volley but hit it over the bar under pressure from the defender.
West Brom had their first chance of the game in the 23rd minute when Blunt fired not far over the bar, but a couple of minutes later Arsenal were ahead in controversial circumstances.
Steven Reid was adjudged to have taken down Santi Cazorla in the box. Certainly he took a wild swipe but made no contact, Cazorla went down and referee Mike Jones pointed to the spot. Mikel Arteta, who missed a last minute penalty to win the game against Fulham, stepped up and fired the Gunners into the lead. 1-0.
At the Stadium of Light Fernando Torres continued where he stopped in the Champions League by scoring a brace to relieve some pressure of the shoulders of new manager, Rafa Benitez.
Juan Mata scored the third as Chelsea finally ended their run of eight games without a win.
In other games, Aston Villa played goalless with Stoke, Swansea lost 4-3 to Norwich and QPR continued their decent run under new manager, Harry Redknapp with a 2-2 draw away at Wigan.
