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. Oxlade-Chamberlain then doubled his tally for the season after he combined with team-mate Olivier Giroud. The result takes Arsenal back above Manchester City, although Manuel Pellegrini's side can in turn regain top spot if they beat Chelsea at Etihad Stadium on Monday.
