Arsenal went back top of the Premier League with victory over a dogged Crystal Palace at Emirates Stadium.
Following a goalless first half, Alex Oxlade-Chamberlain got his first of the season when he finished calmly after intelligent play from Santi Cazorla.
Palace could have had an equaliser but Cameron Jerome's diving header was excellently saved by Wojciech Szczesny.
