Goals from Bacary Sagna and Cesc Fabregas gave Arsenal a 2-1 win at Everton on Sunday to lift them above Manchester United into second place in the Premier League.
Fullback Sagna, with only his second goal for Arsenal in more than 140 matches, opened the scoring when he fired past Tim Howard at the near post after 36 minutes. Fabregas added the second goal three minutes into the second half.
Arsenal, who thrashed Everton 6-1 at Goodison Park on the opening day of last season, dominated for much of the game but had to hang on at the end after Tim Cahill scored for Everton in the dying minutes.
It was Everton's first defeat for eight League matches. They had plenty of chances of their own with Cahill missing a good opportunity with an early header and Jermaine Beckford thwarted after coming on as a 69th-minute substitute for Phil Neville.
Everton's late rally had Arsenal rocking but goalkeeper Lukasz Fabianski also saved well from Steven Pienaar and Louis Saha to prevent the home side equalising.
Arsenal boss Arsene Wenger told the BBC: "It's always very difficult to come here and that is three very important points, based on great spirit, great resilience, more than style.
"These are very important ingredients to be successful. You need those qualities to win the title. The team deserves a lot of credit."
Everton boss David Moyes said: "Overall I can't have any complaints. One or two decisions could have gone the other way but it didn't go for us. I don't think either team were at their best but we never really got hold of the game and we weren't able to generate an atmosphere inside the ground which we normally do."
Chelsea, who were facing Sunderland at Stamford Bridge in a game that kicked off at 1610 GMT, lead the standings with 28 points, with Arsenal on 26 and United third on 25 following their 2-2 draw at Aston Villa on Saturday.
