DC: Per Mertesacker
Not at his best last week, but Per Mertesacker should keep his place in the Arsenal team and will take the captain’s armband.
DC: Laurent Koscielny
An important part of this Arsenal side, Laurent Koscielny will start again this weekend, but will need to play better than he did against West Ham.
MC: Francis Coquelin
Superb in midfield last season, Francis Coquelin will have to show he was not a one-season-wonder with an improved performance against Palacd this week.
MC: Santi Cazorla
In a deep-lying creative role, Santi Cazorla will be influential for Arsenal in this match and will be hoping to score as he did against this side last season.
