The France internationals scored within two minutes of each other in the clash at the Emirates, with their goals proving decisive against Roberto Martinez’s side
Olivier Giroud was among the goalscorers as Arsenal moved to the top of the Premier League with a 2-1 defeat of Everton at the Emirates.
The hosts scored twice in three first-half minutes, Giroud converting Mesut Ozil’s cross before Laurent Koscielny doubled the hosts’ advantage with another fine header.
Ross Barkley pulled one back for Everton with a deflected strike just before half-time but, despite having plenty of chances, Everton could not conjure up an equaliser and their evening ended in further disappointment with the late dismissal of midfielder Gareth Barry for two yellow cards.
Arsene Wenger’s men top the table with 22 points from 10 games but they can be replaced by Manchester City on Sunday should they get at least a draw in the Manchester derby.
Arsenal started the match confidently and threatened for the first time in the eighth minute. Giroud beat his marker to the ball from Santi Cazorla’s corner but the Frenchman failed to get his header on target.
Everton nearly opened the scoring against the run of play on the half-hour mark. Petr Cech failed to adequately deal with Aaron Lennon’s cross from the left, handing John Stones a golden chance to hand the visitors the lead but the England defender blasted wide from close range.
Arsenal grabbed the opener in the 36th minute. Ozil sent in a superb cross for Giroud and the striker beat Phil Jagielka to the ball before heading home from five yards out.
The hosts doubled their lead just two minutes later. Referee Lee Mason awarded Alexis Sanchez a free-kick down the left and Cazorla sent the ball into the box for Koscielny to head past the helpless Tim Howard.
