Southampton beat Stoke 1-0 to jump into second place in the Premier League table as Manchester City lost 2-1 to West Ham. Elsewhere, Arsenal's Alexis Sanchez scored twice as they beat Sunderland 2-0 and Liverpool were held to a 0-0 draw with Hull with Mario Balotelli missing a sitter in the final minute.
Alexis Sanchez made the most of howlers from Wes Brown and Vito Mannone as Arsenal claimed a 2-0 victory at Sunderland.
The Chile international needed no second invitation after Brown scuffed an attempted back-pass straight into his path and looked on in horror as he raced almost half the length of the pitch before beating goalkeeper Mannone with ease.
And there was worse to come for the Italian, who handed Sanchez a second in injury-time as he made a mess of a back-pass.
Once again, the Black Cats, who scored three own goals in last Saturday's 8-0 horror show at Southampton, were made to pay for self-inflicted wounds despite launching a second-half fightback in front of a crowd of 44,449 at the Stadium of Light.
Mario Balotelli and Liverpool fired blanks as Hull held on for a goalless Premier League draw at Anfield.
Much of the focus was on Balotelli after an underwhelming start to his Liverpool career and controversy in midweek after exchanging shirts at half-time in the loss to Real Madrid. But the Italian and his team-mates could not find a way through as Hull frustrated them to prolong the Reds' below-par start to the campaign.
Raheem Sterling, Philippe Coutinho and Balotelli all went close in injury time as Liverpool's dominance of the second half almost brought reward in the closing moments.
Southampton's incredible start to the season continued against Stoke as Sadio Mane's strike propelled them back to second in the Premier League with a 1-0 win.
It was never going to be a repeat of the 8-0 annihilation dished out to Sunderland, but another fine team display saw Saints celebrating a fourth consecutive win at St Mary's.
Mane's first-half strike proved the difference as Stoke were seen off 1-0, making this a better start than the 1983/84 season when Southampton finished the campaign second. In truth, had it not been for poor finishing, Ronald Koeman's men would have won by a much grander scoreline.
Saido Berahino's injury-time penalty rescued a point for West Brom as they fought back from two goals down to draw 2-2 with Crystal Palace.
The striker slammed in his eighth goal of the season after Mile Jedinak had felled Victor Anichebe, who had started the Baggies comeback when he nodded in early in the second half.
Palace were upset, though, as Craig Dawson fouled Julian Speroni to allow Anichebe to score - forcing the keeper off with a head injury.
Brede Hangeland and Jedinak's penalty had fired Palace into a commanding half-time lead.
Palace were also denied what appeared to be a clear first-half spot-kick when referee Mark Clattenburg failed to spot Dawson's foul on Wilfried Zaha.
In the early game, Diafra Sakho's sixth goal in as many Premier League starts gave West Ham a 2-1 victory over champions Manchester City at Upton Park.
The Irons, who had climbed into the top four with a run of positive displays, took a deserved lead through Morgan Amalfitano on 21 minutes as the visitors were outmuscled.
City piled on the pressure, which saw Sergio Aguero hit the crossbar and Yaya Toure strike the outside of the post. However, on 73 minutes, Sakho, signed from Metz in the summer, made it 2-0 when his downward header dropped over the line, given by the Goal Decision System after Joe Hart had clawed the ball out inside the far post.
David Silva hit back immediately to set up a grandstand finale, but West Ham held on as City missed the chance to close up on leaders Chelsea, who visit Manchester United on Sunday.
And in the final game of the day, Wilfried Bony scored both goals as Swansea saw off Leicester 2-0 at the Liberty Stadium.
Bony hit 16 goals in his first season in English football but endured a slow start this time following a summer in which he played for Ivory Coast at the World Cup and saw speculation surrounding his future in Wales.
But the 25-year-old has been back to his best in recent weeks, and ensured Leicester would get nothing from their trip by striking in each half against the shot-shy Foxes.
Bony's second made him the joint highest Swansea scorer in Premier League history, equalling Michu's 20-goal total, and Gylfi Sigurdsson pulled the strings as Garry Monk's men ended a run of five games without a win to climb back into the top six.
