City pay for penalty profligacy as Arsenal move level at top
Pep Guardiola's side missed twice from 12 yards and relinquished their 100 percent home record against Everton as Arsenal saw off spirited Swansea.
Manchester City twice missed penalties in a 1-1 draw with Everton on Saturday as 10-man Arsenal went level with them on points at the top of the Premier League table after seeing off Swansea 3-2.
Arsenal leapfrogged Tottenham Hotspur into second place after their arch north London rivals also dropped points in a 1-1 draw away to West Bromwich Albion.
Everton goalkeeper Maarten Stekelenburg twice dived to his left to save penalties from Kevin de Bruyne and Sergio Agüero -- his second spot-kick failure this week after he was off target in Argentina's World Cup qualifying defeat by Paraguay.
Toffees defender Phil Jagielka gave away both penalties, the first on the stroke of half-time, and it seemed Everton's luck was in when Romelu Lukaku fired the visitors in front in the 64th minute before substitute Agüero's miss.
But City, who've now gone three games without a win in all competitions, equalised in the 72nd minute when Nolito headed in Silva's cross as former Barcelona team-mates turned managers Pep Guardiola and Ronald Koeman had to settle for a point apiece.
Walcott on target again
At the Emirates, Theo Walcott scored twice as Arsenal defeated Swansea for a sixth straight win in all competitions. Walcott struck in the 27th minute after Jordi Amat failed to clear Hector Bellerin's headed cross.
The England international doubled the Gunners' lead seven minutes later following Hull's failure to clear a corner.
Swansea, in former United States manager Bob Bradley's first game in charge, saw Gylfi Sigurdsson equalise in his 100th appearance for the Welsh club with a 38th-minute curling shot
But Mesut Özil marked his 28th birthday by restoring Arsenal's two-goal advantage with a 57th minute-volley.
Swansea substitute Borja Bastón pulled a goal back for the visitors and Arsenal had to play the final 20 minutes a man down after Granit Xhaka received a straight red card.
Chadli back to haunt Spurs
Tottenham dominated possession at the Hawthorns without scoring and were made to pay the price when former Spurs star Nacer Chadli scored eight minutes from time. But Dele Alli's 89th-minute equaliser preserved Spurs' unbeaten league record.
Liverpool will go level with the top two if they beat bitter rivals Manchester United on Monday.
Chelsea hunt foxes at Stamford Bridge
Earlier, Chelsea dealt a fresh blow to champions Leicester City's hopes of a successful title defence with a 3-0 win at Stamford Bridge.
Defeat meant the Foxes have won just two of their eight league games this season and manager Claudio Ranieri said: "We made mistakes...Our approach to the match was not good," the former Chelsea manager added.
The result gave Antonio Conte, Ranieri's fellow Italian, a much-needed win after speculation he was about to be sacked as Chelsea manager.
First-half goals from Diego Costa and Eden Hazard put hosts Chelsea in a strong position before Nigeria international Victor Moses's effort 10 minutes from time set the seal on an impressive win.
"From the start I asked them to play well with intensity and to try to do what we are doing in training," said Conte. "I am very happy because I had a good reply. This is the best game for us."
